Several transients were treated by simulation (start unloading, introducing a torque load, reversing and speed setpoint change). Then engine cushion at both loss and when starting without the damper. In addition, robustness tests on the parametric variation of (MSRB) were also performed. Based on the results of simulations, the control technique studied makes it possible to obtain good dynamic and static performances and has a robustness with respect to the external perturbation and the parametric variation.

The Direct Torque Control (DTC-SVM-Predictive) where the control of the switching frequency is well controlled and therefore the ripples are weakened at the torque and flux levels.
