The paper adopted the TMS320LF2407A micro-processor to design the power conversion circuit, over-current protection circuit and fault detection circuit for 36 kW 12/8 pole switched reluctance motor by studying its control system.According to the requirement of control effect for switched reluctance motor, the paper also designed the double close loop speed regulation control structure.In addition, speed loop of doub-le close loop speed regulation control adopted the fractional order PI regulator.The control program design of phase current chopping control and current regulator control were elaborated mainly in this paper.The de-signed system improves the stability and reliability by considering the hardware and soft ware.
