AbstractThis paper presents a wind-generation system design for rural applications. In Southern areas of Argentina, there are rightconditions for wind energy exploitation. Depending on the characteristics of these areas, the wind-generation systems canoperate either isolated or connected to the grid. This work particularly emphasises the design of a generator to optimise thesystem performance and achieve its minimum volume. The analytical design is evaluated using finite element analysis andexperimentally validated using a 35 kW prototype. The tests reveal that the design procedure is suitable. The initiallyproposed efficiency aim was exceeded, reaching a maximum value of 94.2%. The generator operating conditions make itparticularly suited for the application for which it was designed. © The Institution of Engineering and Technology 2018.

AbstractIs propose an excitation system for autonomous induction generators that feeds non-linear and unbalanced loads. Thegenerator is composed of an induction machine (IM) of the squirrel cage type, the excitation system has a capacitor bankand a four-wire converter connected in parallel with the IM. The control algorithm of the excitation system is based on theInstantaneous Reactive Power theory, which allows the converter to inject the reactive power required for the excitation andvoltage regulation of the IM; also it allows to compensate the harmonics and imbalances introduced by the loads. In thisway, the voltages and currents that circulate through the IM will be sinusoidal and balanced, reducing losses and torqueoscillations, increasing the performance and useful life of the generation system. Simulation results are presented thatdemonstrate the viability of the proposal.En este trabajo se propone un sistema de excitación para generadores deinducción autónomos que alimenta cargas no lineales y desequilibradas. El generador está compuesto por una máquina deinducción (MI) del tipo jaula de ardilla, el sistema de excitación posee un banco de capacitores y un convertidor de cuatrohilos conectados en paralelo con la MI. Como algoritmo de control del sistema de excitación se propone utilizar la teoría dela Potencia Reactiva Instantánea, la cual permite que el convertidor inyecte la potencia reactiva requerida para la excitacióny regulación de tensión de la MI; además permite compensar los armónicos y desequilibrios introducidos por las cargas. Deesta manera las tensiones y corrientes que circulan por la MI serán sinusoidales y equilibradas, disminuyendo las pérdidasy las oscilaciones de torque, aumentando el rendimiento y vida útil del sistema de generación. Se presentan resultados desimulación que demuestran la viabilidad de la propuesta. © 2018 IEEE.

AbstractA control strategy to achieve fault ride-through capability and to provide high performance of the output voltage of a single-phase uninterruptible power supply (UPS) inverter is proposed in this study. This strategy consists in controlling the voltageand current waveforms measured at the inverter output filter, with an inner current control loop and an outer voltage controlloop, using a plug-in structure based on multiple resonant stages in addition with proportional controllers. In order to achievestability from no load to short-circuit conditions, the implementation of the multiple resonant controllers includes a



compensation of the system phase lag. Moreover, it presents a comparative analysis between two controller structures, theproposed plug-in and the classical proportional + resonant. From this analysis, it can be concluded that the plug-in structurepresents improved characteristics of closed-loop output impedance and output voltage dynamic response during fault ride-through events. A controller design methodology to achieve robustness to parametric uncertainties and UPS standardcompliance, is detailed. Experimental results from a single-phase 2 kVA inverter prototype are presented to validate thefeasibility of the proposal. © The Institution of Engineering and Technology 2018.

AbstractA novel decoupling model for a six-phase permanent magnet machine is proposed in this paper. The model considers themachine as two independent three-phase stator windings that are spatially shifted by a generic angle (Formula presented.).The proposed transformation considers the zero sequence and allows the coupling between phases to be eliminated. Theparameters, which define the dynamic behaviour of the model, are calculated with simulations performed using the finite-element method. The decoupled model and the parameters are analyzed for two configurations of a traditional six-phasemachine. Simulation results were validated by experimental results with a simple procedure. © The Author(s) 2018.

AbstractA fault tolerant strategy is proposed to control the power flow in High-Speed Permanent Magnet Machines (HS-PMM) witharbitrary Electromotive Force (EMF) waveform. The strategy aims to minimize ripple torque and reduce reactive power thatflow on the machine. The control algorithm is based on the instantaneous reactive power theory and is implemented with aconventional three-phase four-wire converter. The focus of the work emphasizes the Fault Detection Algorithm (FDA), whichis key to the correct performance of the fault tolerant system. Simulation results are presented to the system when an opencircuit fault occurs and the correct performance of the FDA and the entire system is observed. © 2018 IEEE.

AbstractGenerally poly-phase machines are called those with more than three phases (> 3ph), these have acquired importance inrecent years in specific applications such as wind power, electric vehicles, aeronautics, boat propulsion, etc. Its mainadvantage lies in fractionate power in large machines (ships, wind) and fault tolerance to low power machines (aeronautics,electric vehicles). Because they are special machines, it is complex to acquire them in our country. Therefore, theconversion of two three-phase permanent magnet machines into two six-phase poly-phase machines with two differentwinding configurations is presented. They are aimed at didactic purposes in the Electrical Machines course and in researchtasks. In the present work the process of construction of two poly-phase machines from commercial three - phase machinesis detailed. © 2003-2012 IEEE.

AbstractA droop control strategy to achieve parallel operation of single-phase inverters for UPS applications is proposed in this work.This strategy is based on multiple resonant controllers designed to comply with performance specifications given byIEC62040-3. In order to reduce the circulating current between the parallel connected inverters, the inverters outputimpedances must be increased. For this purpose a damping factor in the resonant controller tuned at the fundamentalfrequency is proposed. A design criteria for this damping factor is proposed based on a state-space model of the whole UPSsystem. Experimental results are presented to validate the proposal. © 2017 IEEE.

AbstractSolar energy is currently an important alternative for electricity generation due to growing demand, shortage of fossil fuels,environmental requirements and technological advances in power electronics. Maximum Power Point Tracker (MPPT)methods are applied to photovoltaic (PV) systems to maximize energy extraction under any environmental conditions and to



control the nonlinear characteristics of its parameters. In this paper we first propose the implementation of basic MPPTtechniques, such as Perturbation and Observation (P&O) and Incremental Conductance (IC), and then improvements aremade in efficiency and precision of extracted power using a Fuzzy control design type Mamdani. These techniques areimplemented in simulation and experimentally validated in a laboratory prototype. © 2017 Comisión Permanente RPIC.

AbstractA dynamic model it is proposed to analyze the stability and the steady-state response of islanded parallel connectedinverters controlled by a droop control strategy. The proposed state space model allows to analyze the effects of the virtualimpedance loop over the system stability boundaries. Furthermore, it enables to establish a compromise relationshipbetween voltage regulation and the circulating current between the parallel connected inverters, which facilitates the designof the virtual impedance loop. To validate the proposal, experimental results obtained in a prototype of two invertersconnected in parallel feeding a 2kW load are presented. © 2017 Comisión Permanente RPIC.

AbstractDesign considerations for a three-port bidirectional DC-DC converter to be used in hybrid energy storage systems (HESSs)with the aim to increase the power transfer capability are discussed in this study. For this, an analysis of the power flow thatallows obtaining the current waveforms is presented. Then, a loss model, that includes losses in semiconductors and themagnetic core, is proposed based as a function of the voltage variations in the energy storage devices considering allpossible cases of power transference. The analysis reveals that it is possible to size the converter auxiliary inductances toreduce the converter currents and losses and therefore increase the power transfer capability. The analysis and theproposal presented in this study are validated using a 5-kW experimental prototype. Results show that it is possible toincrease the converter transfer capability up to 80%. © The Institution of Engineering and Technology.

AbstractA new methodology to design discrete-time multiple resonant controllers for single-phase uninterruptible power supplyinverters is proposed in this study. This methodology is based on classical linear tools and consists on the synthesis of theinverter output impedance according to standard specifications. This synthesis is performed using a multi-loop controlstrategy composed of an inner current control loop using a proportional controller, and an outer voltage control loop usingthe multiple resonant controller. A prototype was built to demonstrate the practical feasibility of the theoretical proposal. Asignificant reduction of the output impedance at determined harmonic frequencies resulted in a low-voltage total harmonicdistortion of the output voltage of about 1.76%, for IEC 62040-3 reference non-linear load. © The Institution of Engineeringand Technology 2016.

AbstractVoltage unbalance and harmonic voltage distortion affect the power, torque and vibrations on induction motors (IM). In thispaper, we compute the frequency of the oscillations of the power, torque and vibrations due to voltage unbalance andharmonics and we present laboratory results to verify the calculations. We also show that typical values of harmonicdistortion combined with the maximum levels of voltage unbalance allowed by standards are sufficient to introducevibrations levels under which continuous operation of IMs is not recommended. This result has important implications forroot-cause analysis of IM trip due to vibrations because protection engineers can rule out mechanical problems by verifyingthat vibrations are only present during high levels of voltage unbalance and harmonic distortion. © 2016 Elsevier B.V.

AbstractThis paper proposes a design of a bidirectional three-port DC-DC converter in order to extend the operating limits when theconverter is used as an interface between a battery bank, a supercapacitor and a dc load. The operating limits aredetermined according to the maximum current on the switches and also by the thermal limit established by the junctiontemperature of the semiconductors. It is shown that the amplitudes of the DC voltages have a significant influence on theoperating limits, which depend on the state of charge of batteries and supercapacitors. Other factors with an importantinfluence on the operating limits are the values of the auxiliary inductances of the converter. © 2015 IEEE.

AbstractA strategy for fault detection and tolerance on the inverter that controls power flow in variable-speed permanent-magnetgenerators is proposed in this paper. The performance of the proposed strategy is analyzed in two different four-wiretopologies. In the first topology, the neutral point of the generator is connected to the middle point of the dc-link capacitorbank, whereas in the second topology, it is connected to a fourth leg of the inverter. The main contribution of this paperresides in the control scheme, which allows a steady operation through a fault occurrence without the need of reconfiguringneither the inverter topology nor the control algorithm. In this way, transients and the use of extra hardware components areavoided. In addition, a control loop that allows limiting the generator losses at any operation point is presented in order toprotect the machine. Finally, experimental results, obtained from a laboratory prototype, validate the practical feasibility ofthe proposed strategy. © 2015 IEEE.

AbstractThe main hypothesis proposed in this paper is that by controlling the harmonic and zero-sequence components of thecurrent in nonsinusoidal permanent-magnet synchronous generators (PMGs), additional energy can be obtained, therebyincreasing the machine power density without increasing the Joule effect losses. Two different strategies are proposed forthree-and four-wire topologies; therefore, four different cases are analyzed. The strategies consist in controlling the PMGstator currents, following a function that depends on the waveform of the back electromotive force (EMF). The currentfunction is obtained from the instantaneous reactive power theory. An experimental system was built to validate theproposal. Experimental results prove that it is possible to increase power in a tested PMG by 7% using the four-wiretopology in comparison with the conventional block commutation and same losses. Higher power gain can be obtained formachines with almost rectangular-shaped EMF waveforms. © 2014 IEEE.

Such control is based on the evaluation of instantaneous power components. First, the conventionalcontrol strategy 6 steps for PMSG in compared with the strategy proposed for 3-wire systems where the latter has theadvantage of minimizes copper losses and reduce torque ripple. Then a 4-wire systems is analyzed, the topologyimplemented connect the neutral point of the generator to the midpoint of the DC bus capacitor bank, in these case, thestrategy proposed can increase the energy transfer exploiting the homopolar current flow.

AbstractThis paper evaluates and compares the performance of a DC-DC converter with dual active three phase bridges using athree-phase high frequency transformer with star-star connection (DAB3YY) and delta-delta connection (DAB3ΔΔ). Theobjective of this comparison is to evaluate the stress of the power semiconductors based on the RMS values and the sum ofthe current as well as the transformer apparent power. From the analysis we conclude that the leakage inductance of thetransformer DAB3ΔΔ should be three times greater than that of DAB3YY to transfer the same power. Furthermore, it isconcluded that the stress on semiconductors and apparent power are the same on both connections, demonstrating thefeasibility of using the DAB3ΔΔ. © 2014 IEEE.

AbstractMost of the electric energy generated is consumed by induction motors (IMs) in the industry. As a consequence, even smallefficiency improvements in their performance yield large energy savings [1]- [4]. To promote the development of even moreefficient IMs, the standard IEC 60034-30 from 2008 specified three efficiency classes [1] [2]. At full load and under idealvoltage supply conditions, IMs in higher efficiency class use less energy than IMs in lower efficiency classes. For example,



IMs in the IE3 class waste at least 30% less energy than IMs in class IE1. However, the behavior of higher efficiency classIMs under distorted and unbalanced voltages is not fully documented [5]-[7]. Initial studies by Van Wyk et al. suggest thathigher efficiency IMs are more affected by voltage supply problems [5]. In this paper we study the effect of voltageunbalance, harmonic voltages and load level on the efficiency of the IM. We analyzed the efficiency of two 4.5 kW 60 HzIMs, one in the standard efficiency class (IE1) and the other in the high efficiency class (IE2). We also analyzed two 5.5 kW50 Hz IMs, one in the standard efficiency class (IE1) and the other in the premium efficiency class (IE3). We used aprogrammable power supply to feed the IMs. We adjusted the wave shape and the unbalance ratio to obtain differentvoltage harmonic distortions and voltage unbalance levels. The IM under test was coupled to another IM driven by acommercial torque-controlled variable-speed drive that acts as a variable load. We measured two phase currents and twoline voltages to calculate the input power. We also measured the mechanical torque and speed to calculate the outputpower and to estimate the efficiency. In the unbalanced voltage tests, we noticed that the efficiency of the premiumperformance IM deteriorated the most as the voltage unbalance grew. This result is consistent with negative sequenceimpedance values estimated from the starting currents of the IMs. For the unbalanced voltage tests, we also found that thedegradation of the IMs efficiency does not change with the loading of the IM. On the harmonic voltage distortion tests, wefound that the efficiency of IMs in the high and premium efficiency classes deteriorated at the same rate as the IMs in thestandard efficiency class. © 2014 CIGRE.

AbstractThe effects of asymmetrical magnet faults on the rotor of Permanent Magnet Synchronous Machines (PMSM) are analyzedin the present work. Two different stator winding configurations, series and parallel connected windings, are considered inthe analysis. From PMSM with parallel windings, a fault detection strategy based on the information contained in the branch-current spectrum is proposed. A fault severity factor is defined to quantify demagnetization on a single magnet. This factor ispractically independent from the motor load conditions.

AbstractIn this paper various five-level active-neutral-point-clamped converters (ANPCCs) are proposed. These, as for theconventional ANPCC structure, are constructed with a combination of neutral-point-clamped and floating capacitor convertertechnologies. Depending on the new circuit arrangement, better total semiconductor conduction losses and/or therequirement of lesser active switch part count are achievable when compared to a conventional ANPCC. Additionally, amodulation scheme providing well regulated, balanced and low voltage ripples across the dc-bus capacitors for the studiedANPCCs is presented. The voltage balancing across the phase capacitors is performed by selecting the multilevel converterredundant switching states, which results in different current direction across this device. The technique is implemented in acarrier-based PWM modulation scheme. © 2013 IEEE.

AbstractThis paper proposes a loss minimization control including fault tolerance for variable-speed permanent magnet synchronousgenerators, for which it is required that power flows stays constant and the generated energy processed through aAC/DC/AC power converter. It propose and compare two different 4-wires topologies. In the first topology, the neutral pointof the generator is connected to a fourth leg of the inverter, and in second topology, it is connected to the midpoint of the DCbus capacitor bank. The main advantage of both options is that once fault occurs, is not necessary to reconfigure theinverter topology which means no need for additional switches. In addition, there is no need for modifying the controlalgorithm during fault. Another characteristic of the proposed control algorithm is that it allows limiting the generator lossesto its maximum admissible value during operation, even under fault conditions. Simulation results are also presented tovalidate the proposed control strategies. © 2012 IEEE.

AbstractThe operation of a Dual Active Bridge (DAB) DCDC converter when one of its power semiconductors presents an opencircuit fault is analyzed in this paper. In order to be able to detect this sort of failure, a new diagnosis strategy is proposed.The strategy consists basically of two stages: 1) measure the voltage drop in each power semiconductor in on-state by aproper modification in the driver circuits and 2) feedback the fault signal generated in the drive circuits to the microcontrollerto decide the next action. Then, the voltage measured is compared with a reference value to determine if a semiconductorpresents an open-circuit fault.

AbstractThe design of a non-linear controller for a three-phase front end converter used to connect renewable energy sources to thegrid is presented in this paper. The objectives of this controller are the injection of all the generated power into the grid andthe control of the reactive power exchanged with the power system. The system is represented through Park-coordinatesand port controlled Hamiltonian models. The controller is designed by interconnection and damping assignment (IDA), andfeedback linearization (FL). It is demonstrated that for the particular case of selecting interconnection and damping matrixes,then coupling can be eliminated from the system model and therefore the controller designed using interconnection anddamping assignment results the same as that using feedback linearization.

AbstractA control method is proposed with the objective of maximizing the energy transference in permanent magnet synchronousgenerators (PMSG). Such control is based on the evaluation of instantaneous power components as well as of theoptimization strategies to obtain the generator reference currents. Two possibilities are studied in the present work: with



connection and without connection to neutral, for generators with three different EMF waveforms. In addition, twopossibilities for each connection type are also presented in this effort. The first strategy has the main objective of generatingat constant power and with minimum losses. On the other hand, the main objective of the second strategy is to get themaximum power while preserving the generator thermal limits. Simulation results are presented and analyzed to validate theproposed strategies. From these results, it can be concluded that when neutral is connected, it is possible to take advantageof the homopolar components of the generator EMF by imposing and adequate current with the objective of maximizing thegenerator power. © 2012 IEEE.

AbstractA stator winding turn fault diagnosis strategy in induction motor (IM) drives is proposed in the present work. This strategy isbased on the effects of the inductance variations coming from fault, over zero-sequence voltage. This voltage is measuredwhen a predefined inverter-switching pattern is applied, allowing then decoupling the strategy from the motor fundamentalexcitation. For the evaluation of the feasibility of this proposal, a multiple-coupled circuit model of the IM is used.Experimental results are included to show the ability of the proposed strategy for detecting incipient faults, including a lownumber of short-circuited turns. © 2011 IEEE.

AbstractA new modulation strategy that allows operating the dual active bridge (DAB) dcdc converter under soft switching in thewhole operating range is proposed. This strategy is ruled by imposing a certain modulation index in one of the two bridgesand a phase shift between the transformer primary and secondary voltages. Moreover, the proposed algorithm reduces thereactive power and thus reducing the converter conduction losses. An experimental prototype was implemented and someexperimental results are presented to validate the theoretical analysis. The experimental results reveal that the overallefficiency of the DAB topology can be improved up to 20 by implementing the proposed modulation strategy instead of theconventional one. © 2011 IEEE.

AbstractThe main objective of the proposed analysis is the detection of inter-turn short circuits in the stator windings of an inductionmachine. The analysis of the space vector current modulus of an induction motor is presented in this paper. This analysis isbased on Daubechies 8 wavelet with seven decomposition levels. The 5th decomposition-level detail signal for a 4 kHzsampling frequency is chosen as a fault indicator, based on simulation results that show different behaviors of the energycontained in the detail signals independent of the percentage of load and fault levels. Experimental results that validate theproposed strategy are also presented. These results also show that the strategy is in addition immune to load variations aswell as to feeding voltage unbalances. © 2011 World Scientific Publishing Company.

AbstractA new control strategy for obtaining the maximum traction force of electric vehicles with individual rear-wheel drive ispresented. A sliding-mode observer is proposed to estimate the wheel slip and vehicle velocity under unknown roadconditions by measuring only the wheel speeds. The proposed observer is based on the LuGre dynamic friction model andallows the maximum transmissible torque for each driven wheel to be obtained instantaneously. The maximum torque canbe determined at any operating point and road condition, thus avoiding wheel skid. The proposed strategy maximizes thetraction force while avoiding tire skid by controlling the torque of each traction motor. Simulation results using a completevehicle model under different road conditions are presented to validate the proposed strategy. © 2006 IEEE.

AbstractIn this work the Multi-Domain model of an electric vehicle is developed. The electric domain model consists on the tractiondrive and allows including faults associated with stator winding. The thermal model is based on a spatial discretization. Itreceives the power dissipated in the electric domain, it interacts with the environment and provides the temperaturedistribution in the induction motor. The mechanical model is a half vehicle model. Given that all models are obtained usingthe same approach (Bond Graph) their integration becomes straightforward. This complete model allows simulating the



whole system dynamics and the analysis of electrical/mechanical/thermal interaction. First, experimental results are aimedto validate the proposed model. Then, simulation results illustrate the interaction between the different domains andhighlight the capability of including faults.

AbstractA scheme for diagnosis and identification of mechanical unbalances and shaft misalignment on machines driven byinduction motors is presented in this work. Fault identification is performed using unsupervised artificial neural networks: theso-called Self-Organizing Maps (SOM). The information of the motor phase current is used for feeding the network, in orderto perform the fault diagnosis. The network is trained using data generated through the simulation of a motor-load systemmodel. Such model allows including the effects of load unbalance and shaft misalignment. Experimental data are laterapplied to the SOM in order to validate the proposal. It is demonstrated that the strategy is able to correctly identify bothunbalanced and misaligned cases. © 2010 IEEE.

AbstractThis study presents a control method for permanent magnet (PM) motors based on a combination of a non-linear full-orderobserver and a signal injection scheme. Stable mechanical-sensorless operating range down to zero speed at full load isobtained using only voltage and current sensors. The signal injection scheme uses the asymmetry of the motor's d and q-axis inductances to estimate rotor position and speed. Such asymmetry is also taken into account in the motor model usedto construct the observer to reduce current estimation error. The performance of the proposed scheme is validated throughexperimental results. © The Institution of Engineering and Technology 2010.

AbstractThe construction of a model that represents the behavior of an Electric Vehicle is studied in detail. The contribution of thiswork is twofold. On one hand an efficient and compact way to model dynamical systems is introduced. On the other hand,the power interchange between the electrical and mechanical sub-models allows a deep understanding of the dynamicsinvolved in electrically driven vehicles. The approach used to model the mechanical parts (chassis, suspension, wheels) andthe induction motors is the Multi-Bond Graph based in models discussed in recent literature. Then these models areintegrated in order to form the complete model that simulates the whole system dynamics. Simulation results are aimed toillustrate the electromechanical interaction (ABS, regenerative braking, etc) as well as the evolution of certain variablesduring a risky situation. Conclusions are obtained based on these results. © Copyright 2011 IEEE - All Rights Reserved.

AbstractA new dynamic model for an induction motor (IM) in abc machine variables is proposed in this work. This model is able torepresent asymmetrical stator core faults (SCF) by modelling them as the variation of the equivalent core loss resistance perphase. One model in qd0 variables and another one in sequence components are deduced and used as tools to analyseand simulate SCF. It is demonstrated that there is a good correlation between SCF severity and the magnitude of the IMstator negative sequence current, impedance and power.

AbstractA sensorless internal temperature monitoring method for induction motors is proposed in this paper. This method can beembedded in standard motor drives, and is based on the stator windings resistance variation with temperature. A small acsignal is injected to the motor, superimposed to the power supply current, in order to measure the stator resistance online.The proposed method has the advantage of requiring a very low-level monitoring signal, hence the motor torqueperturbations and additional power losses are negligible. Furthermore, temperature estimations do not depend on theknowledge of any other motor parameter, since the method is not based on a model. This makes the proposed methodmore robust than model-based methods. Experimental results that validate the proposal are also presented. © 2010 IEEE.

AbstractA new strategy for detection and diagnosis of broken bars and load oscillations is proposed. The proposed technique isbased on the analysis of the instantaneous active and reactive powers spectra, and allows the correct distinction betweenbroken rotor bars and low-frequency load oscillations. A suitable fault severity factor is also proposed, which allows thebroken rotor bar fault quantification, while being practically independent of the motor load. By using the proposed technique,a broken bar fault can be detected and diagnosed, even in the presence of load oscillations at frequencies next to twice theslip frequency. Extensive experimental results, both from laboratory and industrial cases, validate the proposal. © 2010 TheInstitution of Engineering and Technology.

AbstractThe optimization of the supervisory control of hybrid electric vehicles over predetermined driving cycles has been used as aprevious study for determining on-line strategies and also for design and sizing purposes. This problem may be posed as anoptimal control problem, in which the energy in the bank of batteries is often the state variable, and the power from any ofthe system sources is, the control action. As both of these quantities are bounded, the optimal control problem has controlconstraints or state constraints or both. Usually, the charge-sustaining mode of operation is ensured just by imposing atransversality condition, i.e. a fixed final energy, or including an additional term in the cost functional that penalizes themoving away of the state variable from the nominal value. We considered the problem where the state is allowed to movefreely within a band. This led to an optimal control problem with control and state constraints. In this work we describe thedifficulties that arise while solving the equations given by the Pontryagin's Maximum Principle and how these difficulties canbe overcome by using the so-called Direct Transcription approach that consists of a programming tool to solve the resultantlarge-scale finite dimensional optimization problem. © 2010, Institut français du pétrole.

Abstract



In this work a dynamic model of the induction machine that considers the thermal behavior is developed using Bond Graphs(BG). The thermal model is based on considering the slots and teeth as independent elements with their own temperature. Itcorresponds to a real motor used in the tractive wheel of an electric vehicle. The model of the vehicle is also obtained in BGand is coupled to the motor. The complete model allows simulating the whole dynamics in a single model and the analysis ofelectrical/mechanical/thermal interaction is performed. Simulation results are intended to illustrate this interaction underfaulty and healthy conditions in the stator winding. The impact on the mechanical and thermal domain produced by a fault inthe electrical domain is also analyzed. ©2009 IEEE.

AbstractA novel on-line stator care fault diagnosis method for Induction Motors (IM) is proposed. This approach is based on anadaptive state observer; it is derived from the IM dynamic model considering stator iron losses. In this method the ironlosses are represented by an equivalent iron loss resistance (R Fe). Stator core fault causes important variations on ironlosses and these variations are reflected on the (R Fe). Therefore the proposed adptive state observer estimates (R Fe) withthe objective of diagnosis stator core fault. Simulation and experimental results for different fault severity conditions areshowed. These results demonstrated the validity of the method. In addition, simulation results proved that the proposal isnot sensitive to load torque variations. © 2009 IEEE.

AbstractEffects of voltage unbalance on the induction motors power, torque and vibrations are analyzed in this paper. Voltageunbalance produces power oscillations at twice the supply frequency, which introduces, in turn, torque oscillations andvibrations at this frequency. The dependence of these power oscillations on the unbalance level and motor load is analyzedby simulation. The effects of voltage unbalance on the oscillation of motor power, torque and vibrations are extensivelyanalyzed through experimental results. These experiments are performed for induction motors with different rotorcharacteristics, showing that the motor behavior under voltage unbalance significantly changes according to the rotorconstruction. © 2009 IEEE.

AbstractA simple traction control implementation of a Neighbourhood Electric Vehicle (NEV) is presented in this paper. An electronicdifferential traction control is performed using two independent field-oriented controlled Induction Motors (IMs) mounted inthe rear wheels. In order to reproduce a mechanical differential behaviour, an equal-torque traction control is carried outusing only the IM's currents and speeds measurements. A basic self-blocking control is introduced to avoid uncontrolledwheel acceleration during equal-torque control action. The traction system allows energy recovery for batteries duringvehicle braking through the IM's regenerative braking. Standard industrial IMs are rewound to operate on safe low voltage(28 Vrms) and to use standard DC-Link 42V, while maintaining the original motor power. Two three-phase MosFet invertersare built for these motor power requirements. The whole system is controlled using a single digital signal processor,

AbstractIn this paper, a model-based strategy for stator-interturn short-circuit detection on induction motors is presented. Theproposed strategy is based on the generation of a vector of specific residual using a state observer. The vectorial residual isgenerated from a decomposition of the current estimation error. This allows for a fast detection of incipient faults,independently of the phase in which the fault occurs. Since the observer includes an adaptive scheme for rotor-speedestimation, the proposed scheme can be implemented for online monitoring, by measuring only stator voltages and currents.It is shown that the proposed strategy presents very low sensitivity to load variations and power-supply perturbations.Experimental results are included to show the ability of the proposed strategy for detecting incipient faults, including a lownumber of short-circuited turns and low fault current. © 2009 IEEE.

AbstractA rotor flux state observer considering iron loss, for an Induction Motor (IM), is proposed. The aim of this proposal is to avoiddetuning caused by the IM iron loss on a field-oriented control (FOC). An adaptive scheme for the KFe, a parameter thatrepresents the IM iron loss, is also proposed. The main objective of this scheme is to improve the dynamic response ofcontrol by compensating the variations of iron losses due to possible variations in the stator core characteristics. Simulationresults demonstrated that the observer and the adaptive scheme showed a good performance fulfilling then the objectives.© 2008 Elsevier Ltd. All rights reserved.

AbstractBroken rotor bar detection in induction motors using current signature analysis gives good results when the motor load isalmost constant. However, if the load torque is oscillating, or it is a function of the rotor position, the current spectrum will



contain spectral components which coincides with the components produced by rotor faults. Thus, rotor fault detection inthese loads, such as compressors and other reciprocating loads, is very difficult. A new strategy for broken rotor bardiagnosis in single-phase induction motors is presented in this paper. This strategy is based on the analysis of the auxiliarywinding voltage. The proposed strategy allows the diagnostic of rotor faults even with pulsating load torque. Simulation andexperimental results are presented. © 2008 IEEE.

AbstractThis paper presents a control method for permanent magnet (PM) motors based on a combination of a non linear full-orderobserver and a signal injection scheme. Mechanical-sensorless operating range down to zero speed is obtained using onlyvoltage and current sensors. The signal injection scheme uses the asymmetry of the motor's d and q axis inductances toestimate rotor position and speed. Such asymmetry is also taken into account in the motor model used to construct theobserver. The performance of the proposed scheme is validated through experimental results. © 2006 IEEE.

AbstractA strategy for stator-fault diagnosis in induction motors using only voltages and currents measurements is presented in thispaper. The proposed strategy is based on the generation of a vector of specific residual using a state observer. The residualallows the detection of the faulted motor phase and the quantification of the number of short-circuited turns.

AbstractA control strategy to regulate the frequency and voltage of a stand-alone wound rotor induction machine is presented. Thisstrategy allows the machine to work as a generator in stand-alone systems (without grid connection) with variable rotorspeed. A stator flux-oriented control is proposed using the rotor voltages as actuation variables. Two cascade control loopsare used to regulate the stator flux and the rotor currents. A closed loop observer is designed to estimate the machine fluxwhich is necessary to implement these control loops. The proposed control strategy is validated through simulations withsatisfactory results. © 2006 Elsevier B.V. All rights reserved.

AbstractThe performance of interconnection and damping assignment strategy applied to speed control of Permanent MagnetSynchronous Motors is analyzed. It is noted that closed loop performance depends on interconnection and damping valuesinjected by the controller. Certain designs produce nonlinear and coupled dynamics. When it is the case, the motorperformance is degraded since direct current loop is adversely affected by the speed one. Then, from the nominalperformance point of view some selections behave better than other ones. It is demonstrated that interconnection anddamping assignment degrees of freedom can be used for improving the nominal performance. Interconnection assignmentis calculated for constructing speed and direct current decoupled loops. In this case, tracking error dynamics becomes linearand its convergence speed can be adjusted by using the injected damping. Additionally, it is established that interconnectionand damping assignment strategy attaining two decoupled tracking error dynamics loops results in feedback linearization. ©2006 IEEE.

AbstractIn this paper, the application of an additional excitation in induction motor (IM) drives for static, dynamic, and mixedeccentricity diagnosis is proposed. The additional excitation consists in a predefined inverter-switching pattern that isapplied on the motor for a short time, while the fundamental excitation is canceled. This excitation was used previously toimplement a position estimation strategy. The strategy obtains information about the rotor position from the motor saliencieseffects over the zero-sequence voltage. The air-gap eccentricity is a kind of saliency that affects the zero-sequence voltageand allows the use of the additional excitation for eccentricity diagnosis. For the evaluation of the feasibility of this proposal,a multiple-coupled circuit model of the IM is used. The effects of series and series-parallel stator winding connections on thediagnosis signals are shown. Experimental results to validate the proposal are also given. These results show that it ispossible to use the diagnosis strategy in a self-commissioning scheme. © 2006 IEEE.

AbstractA switching control strategy to extend the soft-switching operating range of the dual active bridge (DAB) dc-dc converterunder the zero-voltage-switching (ZVS) operating mode is proposed. The converter topology consists of two active bridgeslinked by a high-frequency transformer. One drawback of this strategy is that soft-switching is only possible in a restrictedconverter operating region. A novel pulse width modulation strategy to extend the conventional soft-switching operatingmode region and its analysis are presented in this paper. Experimental results are given in order to validate the theoreticalanalysis and practical feasibility of the proposed strategy.

AbstractHybrid electric vehicles are those powered from two different sources. Typically, they are equipped with an internalcombustion engine, and also with an electrical storage system, such as a bank of batteries or ultra-capacitors. Whilebraking, these vehicles may convert kinetic energy to electrical energy and send it back to the electrical storage system(regenerative braking). The whole vehicle system may be abstracted to one consisting of two energy sources, one of themrechargeable and the other consumable, that feed or receive energy from an energy consumer. A centralized controlstrategy is required to define the instantaneous power flows among these three main components. In this work, we derivethe power split between the two sources such that fuel consumption is minimized, while the vehicle performs a givenvelocity cycle. Bounds on the power flows from both sources are considered. There is also a constraint of an integral naturethat arises from the fact that the energy of the electrical storage system must remain between proper limits, in order to avoidphysical damage. The problem is posed as a finite horizon dynamical optimization problem with constraints and solved by adynamic programming (DP) approach. The hybrid electrical vehicle being developed in the University of Río Cuarto,Argentina is taken as the case study. © 2006 IMACS.

AbstractSensor count reduction for high-performance induction motor (IM) drives is considered. A novel strategy to compute thethree phase currents, based on a single current sensor and an adaptive observer, is proposed. The observer estimates themotor state variables, allowing then implementing an IM field-oriented controlled (FOC) drive with closed speed loop basedonly on DC-link measurements. To demonstrate the practical feasibility of this proposal, representative experimental results,obtained with a FOC experimental prototype, are presented. The FOC prototype showed results similar to those from aconventional FOC drive with individual phase current sensors. The sensor count reduction achieved represents a significantcost diminution in the implementation of low-power high-performance drives. © The Institution of Engineering andTechnology 2006.

AbstractA new sensorless scheme for high-performance speed control of permanent-magnet ac motors (PMACMs) driving anunknown load is proposed. This scheme uses an extended nonlinear reduced-order observer to estimate the inducedelectromotive force (EMF) and load torque. From the estimated variables, the rotor position, the rotor speed, and theposition derivative of flux are calculated and are used to close the control loop. In order to improve the drive performance,the estimated load torque is incorporated as a feedforward signal in the closed control loop. In addition, the proposedsensorless PMACM drive allows the torque-ripple and copper-loss minimization for motors with an arbitrary EMF waveform.Simulation and experimental results to validate the proposal are presented in this paper. © 2006 IEEE.

It presents the results obtained through numerical simulation with the bi-level dynamic optimization model develop to program the daily operation of a pumped-storage hydroplant in a competitiveElectricity Market with a centralized structure. In the scenario proposed for the demand and valuation of water in the upperreservoir, the model of perfect competition and the model of Cournot achieve in practice the same fuel economy so thereare no differences from the point of view of the competitive pool operator. From the point of view of the competitive poolagent, the pumped-storage hydroplant, the situation is completely different as regards the apportion of benefits resultingfrom each model, being the model of perfect competition more advantageous.

AbstractA novel sensorless speed-control strategy for permanent-magnet AC motors (PMACMs) is presented. A nonlinear reduced-order observer and a high-gain observer are designed to estimate the induced EMF, without mechanical position or speedsensors. In contrast with previous proposals, the EMF estimation is performed without previous knowledge of its waveform.From the estimated EMF, the rotor speed and the position derivatives of flux are calculated and used for the implementationof a PMACM speed control without mechanical position sensor. The proposed strategy is not limited to PMACM withsinusoidal or trapezoidal EMF waveform. Moreover, it allows the PMACM ripple torque and copper losses to be minimised.The performance of the proposal is validated through simulation and experimental results. © IEE, 2005.

Abstract



The effect of rotor faults, such as broken bars and end-rings, over the signals of a position estimation strategy for inductionmotor drives is analyzed using a multiple coupled circuit model. The objective of this analysis is to establish the possibility ofusing the estimation strategy signals for fault diagnosis in variable-speed electric drives. This strategy is based on the effectproduced by inductance variation on the zero-sequence voltage, when exciting the motor with a predefined inverterswitching pattern. Experimental results illustrate the feasibility of the proposal. © 2005 IEEE.

AbstractThe application of an additional excitation in induction motor drives for static, dynamic and mixed eccentricity diagnosis isproposed. The additional excitation consists of a predetermined inverter-switching pattern applied while the fundamentalexcitation is cancelled. This excitation has been previously used to implement a position estimation strategy. This strategyobtains information about the rotor position from the machine saliencies effects over the zero sequence voltage. The air-gapeccentricity is a saliency that depends on the rotor position. For such reason, it also produces changes over the zerosequence voltage. In order to evaluate the feasibility of this proposal, a multiple coupled circuit model of the induction motoris used. Experimental results that validate the proposal are also presented. © 2003 IEEE.

AbstractA non-linear reduced order observer for estimating the rotor speed and position for Permanent Magnet Motors is presented.The EMF is estimated first assuming only that it can be approximated by a Fourier series. Then rotor position and speed arereconstructed using the relationship between the EMF and the rotor variables. The EMF generated by the motor, which isneither sinusoidal nor trapezoidal, is obtained experimentally off-line. Then, it is approximated by a Fourier series in order toconstruct the model to be estimated on-line. The proposed observer is ideal for the realization of torque control withminimum torque ripple, since it allows an easy synthesis of non sinusoidal currents. The proposal is validated withexperimental results.

AbstractIn this paper, a strategy to control an induction generator (IG) working with variable speed and load is presented anddiscussed. An inverter and a field-oriented controller are used in order to excite the induction machine (IM) efficiently,minimizing copper and iron losses, and to regulate the generated voltage. The proposed IG system is a stand-alone (notgrid connected) system. It is used to produce electrical dc energy, to charge a battery bank, and/or to supply dc loads withmaximum efficiency. A laboratory setup, based on a conventional 4-kW squirrel-cage IM, has been implemented.Experimental results are presented in order to validate the proposed strategy.

AbstractIn this work, a new Induction Generator System (IG), to work with variable speed and load, is proposed. The objective is tomake it work as a stand alone (not grid connected) generator to produce constant voltage and variable frequency ACcurrent. The IG is based on a three-phase Induction Machine (IM) exited, simultaneously, by a capacitor bank and a field-oriented controlled inverter. The inverter manipulates the IG excitation currents to control the generated voltage. Thecapacitor bank is used to minimize the inverter current and to filter voltage harmonics. A laboratory set up was mounted toexperimentally validate the proposal. This prototype is based on a 4 kW conventional squirrel cage IM. The inverter usesIGBTs and the controller was implemented using a conventional PC and adequate interfaces. Experimental results arepresented to validate the proposed strategy. This system can be used in variable-speed micro wind or hydro power plantswhere the prime mover operates within a variable speed range to get a better efficiency.

AbstractAlthough many papers about Field-Oriented algorithms can be found in the literature, just one work that discusses the IronLosses Influence on a Field-Oriented Controller (FOC) [1] have been found by the authors. In this paper a new proposal toexplain the same subject is presented. Two induction Machine (IM) mathematical dynamic models are presented. Then,using these models the error on the flux and torque estimation that occur in a conventional FOC algorithm, when the ironlosses are not considered, is analyzed and quantified. Finally, an algorithm to minimize this error is proposed.

AbstractTwo methods of induction motor control are examined. The indirect field-oriented (IFO) and the slip-control (SC) methodsare formally compared. Their block diagrams are derived, analyzed and their similarities shown. It is demonstrated that thedifference between the two is just due to a feedforward block that computes the current phase to be supplied to the motor inan IFO controller. This proves that the implementation complexity of either controller is almost identical. To performcomparative tests, both control methods were implemented using a single hardware. The torque rise time and frequencyresponse of the speed control are presented. Based on experimental results, it is shown that the speed sensor resolutionand the sampling rate of the controller strongly influence the dynamic response in the IFO method. The SC method is lesssensitive to these parameters although it always presented a worse dynamic response. The IFO speed control presented aflat frequency response whereas the SC method presented a peak which could lead to an oscillatory speed response. It isalso shown that the variation of the rotor electrical time constant influences strongly and in a similar way both controlmethods. Finally, it can be concluded that the implementation complexity of both control strategies are almost identical,although the IFO control method has a much better performance than the SC control method. © 1994 IEEE

AbstractThe induction motor (IM) is a high-efficiency machine when working close to its rated operating point. However, at torquesand/or speeds far from the rated values the efficiency is greatly reduced. In this work a new approach is proposed thatminimizes the total copper and iron losses in a variable speed and/or torque IM drive, while keeping a good dynamicresponse. This method is based on a simple IM model that includes iron losses. The model, which only requires theknowledge of conventional IM parameters, is referred to a field-oriented frame. Using this model, the IM losses arequantified and an algorithm, based on a field-oriented scheme, is deduced. Simulation and experimental results arepresented to validate the proposed method. © 1994 IEEE

Comparing the indirect field-oriented-control with a scalar method(1991) IECON Proceedings (Industrial Electronics Conference), 1, pp. 475-480.

AbstractThe indirect field-oriented (IFO) control and the slip-controlled (SC) method are considered. Their block diagrams andexperimental results are analyzed and compared. It is shown that the block diagrams are similar. Their difference lies just ina feedforward block, called the phase regulator block, that gives the current phase to be supplied to the motor in an IFOcontroller. To perform comparative tests, both control techniques were implemented using the same hardware blocks. Thetorque time response, the frequency response of the speed-controlled drive, and the influence of the rotor electrical timeconstant for both control methods are analyzed based on experimental results. The main conclusion is that theimplementation difficulties and cost of both control strategies are quite the same, although the IFO control method has amuch better performance than the SC control method, as expected.
