Nonlinear Sensorless Control of Doubly Fed Induction Machines in Electric Vehicles

This article addresses a sensorless control design based on an extended Kalman Filter (EKF) to estimate the state of a doubly-fed induction motor (DFIM) model. This kind of motor is operating as an actuator in electric vehicle (EV) with optimal performance. Thus, a nonlinear model is adopted to simultaneously allow a simpler observability system analysis and a more effective state estimation. The obtained results clearly show both better performance of this suggested control, and the structure of power provided to the machine.

Comparison study of two FTCs strategies for double stator induction machines

This study aims to apply the two strategies of active fault tolerant control (FTC) by the sliding mode observer (SMO)
and the extended kalman filter (EKF) for direct torque control (DTC) of the double stator induction motor (DSIM) to improve
the performance of the machine. To demonstrate the efficacy of the proposed approaches, a comparative analysis was conducted
between the two suggested strategies in this paper. Several results prove that the two strategies applied with faults, SMO-FTC
and EKF-FTC, improve the robustness and the quality of dynamic responses of the DSIM in closed loop system.

Study of an electrical energy production system coupling a photovoltaic field

The subject is part of significant improvements in the production of electrical energy, more particularly to increase energy yields based on an electromechanical system (ELMS) while contributing to the establishment of essential commercial institutions and frameworks, in the gas and energy sector. To achieve this objective, the solution is to couple the ELMS and the energy storage system.
In this thesis, we interested in the flywheel, a storage system allowing the conversion of electrical energy into kinetic form and vice versa based on a self-excited synchronous generator. The flywheel is driven by an asynchronous motor coupling a photovoltaic field. In this study, the test system is presented as well as the results obtained in closed loop on the system performance.

ANFIS Controller MPPT Algorithm for Solar powered Dual ThreePhase Induction Motor based EVs

In this paper, an adaptive neuro-fuzzy inference system (ANFIS) based maximum power point tracking algorithm (MPPT) are proposed for
solar powered dual three phase induction motor (DTPIM) drives via input-output linearization control (IOLC). The maximum power delivery to the
DTPIM is achieved by MPPT controller which employs ANFIS. It adjusts the duty cycle of the three-level boost converter for extracting maximum
power from solar PV array. In addition, ANFIS is proposed for better performance of the system because has many inputs and also has multiple
outputs but the fuzzy logic has multiple inputs and single output, so the combination of this two is known as ANFIS which is utilized for nonlinear
applications. In order to test the performances of this control, a dynamic emulator is used. Further the propose controller is applied for electrical
vehicle (EV) to determine its performance. Finally the obtained results show that the proposed controller provide a good trajectory tracking, and this
scheme is robust with respect to parameter variations, and external load disturbances for DTP induction motor drive system.

Sensorless ANFIS-Based Control of PV-Powered Double Stator Induction Motors for EVs

This paper propose a robust ANFIS based on Luenberger observer for sensor-less control of DSIM drives via backstepping control (BC) and supplied by a photovoltaic solar. The maximum power delivery to the DSIM is achieved by boost converter which employs P&O MPPT controller. It adjusts the duty cycle of the three-level DC-DC boost converter for extracting maximum power from PV array. In addition, ANFIS is used in this study to ameliorate the performance of this sensor-less control. However, to enhance the performances of this control, we used an EV based dynamic emulator. Thus, we sized and tested the global system under different metrological conditions. In Addition, we have highlighted the comparative analysis between the suggested ANFIS-LO and conventional observer. Finally, the obtained results show the efficiency of the suggested control scheme and the improvements of ANFIS controller based on LO in a DSIM drive system.

This paper deals with the design of a luenberger observer for estimating the state of a doubly fed induction motor (DFIM) model, and for sensorless control of systems employing this type of motor as an actuator in electric vehicle (EV) with optimal performance. Therefore, this paper is concerned with the traction system based electric vehicle, which constitutes a DFIM for a traction motor and a separately excited DC machine (DCM) for an emulated system of EV. The results show the good performance of the sensorless control, and the structure of power applied to the DFIM.

NONLINEAR FAULT TOLERANT CONTROL OF DUAL THREE-PHASE INDUCTION MACHINES BASED ELECTRIC VEHICLES

This paper proposes a robust fault-tolerant control (FTC) for the dual three-phase (DTP) induction machines under failures and which is controlled by a higher-order sliding mode control strategy. However, the DTP induction machine is increasingly used because of its advantages such as better reliability and supply division, both passive and active FTC laws have been designed and tested on DTP. The proposed method not only realizes the FTC and the fault elimination as well but also provides a possible solution for emulating a traction system using a direct continue machine (DCM) supplied by a four-quadrant chopper. Therefore, the emulation system is based on a controlled DCM, which imposes the same behavior of the mechanical power train of an electric vehicle to the DTP. Simulation results are given to verify the robustness and good performance of the proposed fault-tolerant control scheme.

Comparative study of different-fault-tolerant control strategies for three-phase induction motor

In this paper, we have studied a different fault tolerant control (FTC) strategies for a three-phase induction motor (3p-IM).
Further we introduce Backstepping controller (BC) and Input-output linearization controller (IOLC). To provide a direct comparison
between these FTCs approaches, the performances are evaluated using the control of 3p-IM under failures, variable speed, and variable
parameters. A comparison between the two control strategies is proposed to prove the most robust one. The simulation results show
the robustness and good performance of the fault tolerant control with Input-output linearization controller compared to one with
Backstepping controller. The FTC with IOLC is more stable and robust against failures, load torque perturbation and speed reversion.

Véhicules Electriques

Depuis plusieurs années, la traction électrique est devenue un thème de recherche d’actualité.
Ce concept englobe un large domaine de connaissances pluridisciplinaires. Il faut maîtriser
l’électrotechnique, l’électronique, l’automatique, la mécanique et l’informatique sans oublier la chimie
pour les batteries de plus en plus moins encombrantes. Les voitures électriques sont de plus en plus
considérées comme le moyen par excellence pour réduire l’impact de la circulation automobile sur le
climat. Est- ce réaliste ?. Les voitures électriques sont en effet plus efficaces d'un point de vue
énergétique, moins polluantes et permettent l’utilisation de différentes sources d’énergie, y compris les
renouvelables. En tant que telles, elles peuvent (et doivent) contribuer dans une importante mesure et à
long terme au transport durable.
Le véhicule électrique suscite actuellement un regain d’intérêt car il présente l’avantage d’être
non polluant. Sa vocation urbaine est d’autre part renforcée par le fait qu’il présente un agrément de
conduite évident : silence et absence de passage de vitesse

A Comparison of Fault-Tolerant Control Strategies for an Induction Motor

In this paper, a passive fault tolerant control (PFTC) strategies are proposed for an induction motor (IM). Further we introduce Backstepping control (BC) and Input-output linearization controls (IOLC). To provide a direct comparison between these FTCs schemes, the performances are evaluated using the control of IM under failures, variable speed, and variable parameters. A comparison between the different control strategies is proposed to prove the most robust one.
Finally, the obtained simulation results show the superiority of the fault tolerant control with Inputoutput linearization control compared to one with Backstepping control. The PFTC with IOLC is more stable and robust against failures, load torque perturbation and speed reversion.

Comparative study between luenberger observer and extended kalman filter for fault-tolerant control of induction motor drives

In this paper, a robust active fault tolerant control (AFTC) scheme is proposed for induction motor drives (IMD) via input-output linearization control (IOLC) and nonlinear observer. In order to estimate the states and to reconstruct the faults, two different observers are used; a Luenberger observer (LO) and an extended kalman filter (EKF). Further we introduce
feedback linearization strategy by choosing the output function as the rotor speed and flux square. To provide a direct comparison between these FTCs schemes, the performance is evaluated using the control of IMD under failures, variable speed, and variable parameters, finally the obtained results show that the proposed controller with the proposed observers
provides a good trajectory tracking, and these schemes are robust with respect to faults, parameter variations, and external load disturbances for induction motor drive system.

Emulateur programmable de conditions de charge d'un VE

La dégradation de la qualité de l’environnement a conduit ces dernières années la majorité des États à prendre des mesures pour réduire les émissions de polluants. Pour contribuer à une amélioration de la qualité de l’air, le véhicule électrique est une option technologique envisageable. La réalisation d’un dispositif émulateur pour l’émulation du véhicule devient de plus en plus essentielle en raison de la faiblesse de l’opérateur humain de tester et vérifier les performances de ce système d’entrainement en temps réel,qui est une conséquence de la complexité de ce système car les phénomènes mis en jeu dans la transmission des efforts par le pneumatique sont complexes et varies. En fait,nous nous intéressons obligatoirement au dispositif émulateur, ce qui permet de l’émulation de façon précoce à base une association machine-convertisseur, chose qui représente l’un des moyens sur pour contribuer à l’amélioration du rendement des différentes parties de la chaîne de traction du véhicule électrique. En effet, ce travail consiste à étudier un banc de test d’actionneur de traction d’un véhicule électrique à base d’un dispositif émulateur de caractéristiques de charge du véhicule.

Backstepping design for fault detection and FTC of an induction motor drives-based EVs

This paper proposes an improved sensorless fault-tolerant control (FTC) for high-performance induction motor drives (IMD) that propels an electric-vehicle (EV). The design strategy is based on the Backstepping control (BC). However an appropriate combination of the BC and extended kalman filter (EKF) is done, this later is designed in order to detect and reconstruct the faults and also to give a sensorless control. Then, additional control laws, based on the estimates of the faults, are designed in order to compensate the faults. The results show the superiority EKF in nonlinear system as it provides better estimates for faults detection. A classical EV traction system is studied, using an IMD. Indeed, the IMD based powertrain is coupled to DC machine-based load torque emulator taking into account the EV mechanics and aerodynamics. Finally, the effectiveness of the proposed strategy for detection of faults, and FTC of the IMD is illustrated through simulation studies

Sensorless Fault Tolerant Control of an Induction Motor Based Electric Vehicle

This paper describes a sensorless fault-tolerant control (FTC) for a high-performance induction motor drive that propels an electric-vehicle (EV). The effect of the fault on the induction motor (IM) can be modeled by an exogenous signal from a stable autonomous system. An additive term is added to the nominal offset and serves to control the effect of the defect (FTC aspect). The proposed sensorless FTC for IM is realized in presence of both rotor and stator electrical faults. Consequently,

Sensorless second-order sliding mode control of Induction Motor

This paper presents the use of a higher order sliding mode scheme for sensorless control of induction motors (IM). The sliding mode approach is used both for control and for generating the rotor speed and the rotor flux estimates necessary for the controller, based only on the measurements of stator voltages and currents. The second order sliding mode control (SOSMC) is based on a super-twisting algorithm. Then, the proposed control scheme and the observer are tested on an experimental setup confirming their convergence properties. The used observer converges in a finite time and permits to give a good estimate of flux and speed even in presence of rotor and stator resistance variations.

Backstepping fault tolerant control for induction motor

This paper deals with fault tolerant control (FTC) for a high performance induction motor (IM) based on backstepping strategy implicitly tolerant to defects assuming the effect of the fault on the system (IM) can be modeled by an exogenous signal from a stable autonomous system. An additive term is added to the nominal offset and serves to control the effect of the defect (FTC aspect). This additive term is derived from the internal model whose role is to reproduce the signal representing the effect of the defect (FDI aspect). The proposed fault-tolerant controller for IM may be realized in presence of both rotor and stator electrical faults. Simulation tests confirm widely the feasibility and the effectiveness of the proposal FTC of IM based on the backstepping control.

A fault-tolerant control for induction-motors using sliding mode scheme

This paper presents an innovative way using the design of fault-tolerant control (FTC) systems for induction motor (IM). It will be shown how the nonlinear output regulation theory can be successfully adopted in order to design a regulator able to offset the effect of all possible faults which can occur in IM drives and, in doing so, also for faults tolerant control process. This regulator is designed by embedded the internal model fault. The proposed fault-tolerant controller for induction motors (IM) may be realized in presence of both rotor and stator electrical faults. Simulation tests confirm widely the feasibility and the effectiveness of the proposal FTC of IM based on the SMC.
