Abstract :
In this paper a theoretical analysis of switched reluctance motors (SRMs) position servo system is discussed based on the inherent structure of SRM. Because of large step angle of SRM the position precision is influenced. A microstep control strategy is proposed in this paper to decrease the step angle and improve the position precision. A fuzzy logic based controller is designed to realize the position control. Simulation shows that this method can effectively improve the positioning precision of the position servo system and can reduce the torque ripple.
