Torque ripple minimization of SMC drive for an innovative electric naval propulsion system

This paper deals with torque ripple minimization using a degree of liberty offered when the Doubly Fed Induction Machine is employed in Electrical Naval Propulsion. Various strategies have been carried out on the analysis and the reduction of torques ripples. The torque ripples can be reduced by either the machine design or control methods. The authors introduce a new technique to decrease its torque ripples using the control strategy. Simulation results and experimental tests are presented and discussed.
