—This paper proposes a strategy to minimize the losses of an induction motor propelling and Electric Vehicle (EV). The proposed control strategy, based on a Direct Flux and Torque Control (DTC) scheme, utilizes the stator flux as control variable and the flux level is selected in accordance with torque demand of the EV to achieve the efficiency optimized(More)
—This paper presents system modeling, analysis, and simulation of an electric vehicle (EV) with two independent rear wheel drives. The traction control system is designed to guarantee the EV dynamics and stability when there are no differential gears. Using two in-wheel electric motors makes it possible to have torque and speed control in each wheel. This(More)
In this paper a new robust adaptive control algorithm for AC machine is presented. The main feature of this algorithm is that minimum synthesis is required to implement the strategy. The MCS algorithm is a signifiant development of MRAC and is similary based on the hyperstability theory of Popov. The hyperstability theory guarantees the global asymptotic(More)
Direct torque control (DTC) is known to produce fast responses and robust control in AC adjustable-speed drives. However, in the steady-state operation, notable torque, flux, and current pulsations occur. In this paper, nonlinear DTC of induction motor drives is presented based on a space vector pulse-width modulation scheme combined with the input-output(More)
This paper presents the analysis and simulation of the control of double star induction motor, using direct torque control (DTC) based on model reference adaptive control algorithm (MRAC). The DTC is an excellent solution for general-purpose induction drives in very wide range the short sampling time required by the TC schemes makes them suited to a very(More)
In the last years, the alternative energy resources and the fuel cell based distributed generation (DG) system applications have attracted increased interest. This paper investigates a doubly Fed Induction Generator (DFIG) wind turbine and a Fuel Cell (FC) based DG system. The modeling and the control of a hybrid DFIG WT/FC system are presented. The system(More)
In this paper, we are interested in the control of a Doubly Fed Induction Machine (DFIM) operating in motor mode. The proposed structure is based on the association of passivity and fuzzy control. The main objective of this configuration is to optimally regulate the motor speed according to variable references as well as tracking of the time-varying speed,(More)
This paper presents the two dimensional numerical modeling of the coupling electromagnetic-hydrodynamic phenomena in a conduction MHD pump using the Finite volume Method. Magnetohydrodynamic problems are, thus, interdisciplinary and coupled, since the effect of the velocity field appears in the magnetic transport equations, and the interaction between the(More)

Abstract In this paper, a dynamic model of a piezo-actuator based on Coleman-Hodgdon (C-H) hysteresis model is considered. The hysteresis model is(More)
This paper describes the comparative study between two machines, a double fed induction machine and a double star induction machine, using direct torque control (DTC). In a double feed induction machine (DFIM), the stator is feed by a fixed network while the rotor by a variable supply which can be either a voltage or current source and in a double star(More)
