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)
In this paper a decoupled control of a doubly-fed induction machine used in generation mode (DFIG) is presented. It provides decoupled regulation of the primary side active and reactive power and it is suitable for both electric energy generation and drive applications. The mathematical model of the machine written in an appropriate d-q reference frame is(More)
The use of an Electric Differential (ED) constitutes a technological advance in vehicle design along with the concept of more electric vehicles. EDs have the advantage of replacing loose and heavy mechanical differentials and transmissions with lighter and smaller electric motors directly coupled to the wheels via a single gear or an in-wheel motor.

This paper proposes a Sensorless Direct Torque Control (SDTC) neural network traction control approach of an Electric vehicle (EV) without differential gears (electrical differential system). The EV is in this case propelled by two induction motor (one for each wheel). Indeed, using two electric in-wheel motors give the possibility to have a torque and(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)
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 generalpurpose induction drives in very wide range the short sampling time required by the TC schemes makes them suited to a very(More)
In this paper, a dynamic model of a piezo-actuator based on Coleman-Hodgdon (C-H) hysteresis model is considered. The hysteresis model is established by identification considering the particle swarm optimization (PSO) technique. The identified model is tested considering a classical PID controller in order to achieve a tracking control of nano-positioning(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)
