Evaluation of torque sharing functions for torque ripple minimization of switched reluctance motor drives in electric vehicles

Generic algorithm is used to optimize the turn-on angle and overlap angle and the torque ripple factor is selected as the fitness function. Four types of torque sharing functions for switched reluctance motor drives are evaluated by using the torque ripple factor. The investigation shows that the cubic torque sharing function is the prime choice in consideration of the minimum torque ripple, the simplicity and speediness of real-time computation. Therefore, this paper provides a valuable guide for selecting the appropriate torque sharing function to implement torque ripple minimization in switched reluctance motor drives.
