TORQUE-RIPPLE MINIMIZATION IN SWITCHED RELUCTANCE MACHINES OVER A WIDE SPEED RANGE

A torque-ripple minimization technique for switched reluctance motors (SRM's) is presented. The technique is particularly suitable for appli cations requiring wide speed range of operation. A new, simple, yet ef ficient commutation strategy is proposed. The commutation algorithm is speed dependent and uses a real-time approach instead of precalculate d stored data. The model used for the SRM in the controller can also t ie updated in real time. Simulation and experimental results verify th e feasibility of implementing the proposed control algorithm in real t ime.
