Torque ripple minimization in switched reluctance machines over a wide speed range

A torque ripple minimization technique for switched reluctance motors (SRM) suitable for applications requiring wide speed range of operation is presented. A new, simple, yet efficient commutation strategy is proposed. The commutation algorithm is speed dependent and uses a real-time approach instead of precalculated stored data. The model used for the SRM in the controller can also be updated in real-time. Simulation and experimental results verify the feasibility of implementing the proposed control algorithm in real-time.
