Direct torque control scheme for nine switches inverter fed two induction motors-based more electric vehicle powertrains

This paper deals with a direct torque control for nine switches inverter fed two induction motors-based electric vehicles (EVs). In EVs application, the developed system will decrease the installation cost and weight (power electronic devices, position sensors, and mechanical differential). In this context, an adaptive direct torque control of nine switches Inverter which feeds two induction motors is proposed in order to ensure a separate control of two driving wheels and stability for the vehicle when cornering or under slippery road conditions. The experimental tests using dSPACE 1104 card are carried-out to demonstrate the feasibility and effectiveness of the proposed control solution, in terms of robustness and stability.
