Direct torque control of induction machine fed by 5-level flying capacitor inverter with active balancing strategy for electric vehicle application

In electric vehicle (EV), control strategies play a key role in vehicle dynamic behavior and stability. The traction chain considered in this article consists of a multilevel inverter, an induction machine (IM) and open differential. The proposed control strategy is based on DTC drive. Moreover, In this paper we present, on the one hand, the contribution provided by 5-level flying capacitor inverter with active balancing in DTC control and, on the other hand, the application of the global structure proposed with 7 degrees of fredom (7-DOF) EV model. Computer simulations were performed using the Matlab/Simulink environment to evaluate the performance of the proposed control.
