The aim of this paper is the developments a DC/DC boost converter use to powered a DC/AC inverter with induction motor. A strategy of control of an induction motor (IM) used as a propulsion system of an electric vehicle (EV). The boost converter ensures an energy flux for an ideal operation of the vehicle even in case of battery voltage drop. The technique proposed is based on a direct flow and torque control diagram (DTC) and also introduces the fuzzy logic control (FLC) as well as the regulator in the place of a conventional PI regulator. The proposed approach covers the vehicle's torque demand and it optimizes the training performance. Simulation results on a test vehicle propelled by 38-kW induction motor showed that the proposed control approach operates satisfactorily. The analysis and simulations lead to the conclusion that the proposed system is feasible and can be tested on experimental bench.

The aim of this paper is the developments a strategy of control of an induction motor (IM) used as a propulsion system of an electric vehicle (EV). The proposed strategy at different operating conditions using a direct torque control (DTC) technique combined with an Artificial Neural Network (ANN) utilizes the stator flux as control variable and the flux level is selected in accordance with torque demand of the EV to achieve a high drive performance. Simulation results on a test vehicle propelled by two 38-kW induction motors showed that the proposed control approach operates satisfactorily. The analysis and simulations lead to the conclusion that the proposed system is feasible and can be tested on experimental bench.

This paper presents a study of the hybrid system consisting a three energy sources, namely wind energy, photovoltaic power source PV and Battery. Each of the three energy sources is controlled so as to deliver energy at optimum efficiency. A multilevel inverter was used in the system to improving the quality of energy injected into the AC load. Fuzzy logic control is used to achieve maximum power to a DC bus voltage. A management system is designed to manage the power flow between the system components in order to satisfy the load requirements. The considered system was implemented in the Matlab/Simulink, the results show the effectiveness of the proposed method and can be realized with experimented setup.

This paper investigates a dual star synchronous machine powered by two independent threelevel voltage source inverters integrated in a wind turbine system (Figure 1). The dual star synchronous machine is used in areas of high power industrial applications such as naval propulsion, traction systems and renewable energy. This use is motivated by several important advantages compared to classical three-phase machine. In this work, the machine side converters control the dq component current by a conventional method based PI regulator, and then the load side converters control the DC bus voltage using sliding mode approach and the RMS voltage load. The validity of the proposed control technique is verified by Matlab/Simulink. Simulation results presented in this paper confirm the validity and feasibility of the proposed control approach, and can be tested on experimental setup.
