Abstract :
Because of its geometric and electromagnetic structure, the switched reluctance motor (SRM) naturally creates torque ripples during the commutation of the currents from one supply phase to another. We show in the paper that classical linear controllers cannot eliminate these torque pulsations. Thus, we propose a method to remove the torque ripples by applying a torque nonlinear control associated with a suitable phase commutation strategy. Indeed, a precise analysis of the phase commutation, permitted us to present a solution taking into account the currents gradient limitation due to the motor-converter set as well as the sampling effect. Finally, the effect of the modeling errors on the robustness of this control has been verified
