Currently has been successfully used in electric vehicle drive system, household appliances, industrial application, servo system, highspeed drive, aerospace, etc, bee ac motor speed control system, dc motor speed control system and brushless dc motor control system of strong petitors. Switch reluctance motor driving speed in the field has been widely used in power, but also more and more field, caused a lot of experts and scholars of interest. This paper first introduces a switched reluctance motor speed control system (SRD) history, advantages, research direction and application, Condition, and the SRM features and electromagic principle, from the basic laws of electromagic, the principle and the related theory SRD). Using the mathematic model and the model, SRM SRD system model, the current controller model, inverter model, the Angle control model, and through MATLAB simulation and parison analysis and simulation of the ideal mathematical model.
