Paper title: A FUZZY LOGIC APPROACH BASED DIRECT TORQUE CONTROL AND FIVE-LEG VOLTAGE SOURCE INVERTER FOR ELECTRIC VEHICLE POWERTRAINS

Author(s): ABDELHAKIM DERBANE, BEKHE¤RA TABBACHE, AIMAD AHRICHE,

Abstract:

In this paper, a fuzzy logic approach is combined with direct torque control (DTC) for dual-motor based electric vehicle powertrain. The proposed structure is based on five-leg voltage source inverter (FLVSI) and two induction motors. The shared-leg switching-signals are selected by using a fuzzy logic controller in order to ensure an independent control of the two driving wheels. Indeed, the selection of the control sequence duration is performed based on the power demand and the load torque of each motor, Simulation results are carried out to confirm that both of IM is able to operate at different speeds with any load condition.

Keywords: Five leg inverter (FLI), Direct torque control (DTC), Fuzzy logic controller (FLC), Electric vehicle (EV)
