This paper illustrates the operation principle of switched reluctance motor, the switched reluctance motor are analyzed, and summarize the advantages compared to other switched reluctance motor speed control system, embodies the superiority. General motor control algorithm is completed by establishing the mathematical model of the switched reluctance motor's design, to get the theoretical basis. The SRD control system hardware and software system is designed, according to the design idea of mechanical and electrical integration of the combined together to form a high performance speed control system.
