英文摘要： The fault diagnosis of stator windings in Switched Reluctance motor, the fault diagnosis of power converter and the fault diagnosis of rotor position detector will be researched by theoretical analysis, semi-physical non-linear simulation including software synchronized simulation, hardware synchronization and prototype experiments. On the basis of identification and induction of a variety of fault in Switched Reluctance motor drive, the fault characterization discipline of inter-phase short circuit of stator winding, short circuit of the coils to ground, open circuit of phase winding, short circuit of phase winding, short circuit of coil and inter-turn short circuit of a coil in the motor, the fault characterization discipline of short circuit of main switches, open circuit of main switches, short circuit of freewheeling diodes and open circuit of freewheeling diodes in the power converter, and the fault characterization discipline of single sensor failure, multiple sensors failure, abnormal output signals in the rotor position detector will be shown. The theoretical criterion of the faults will be obtained. The semi-physical non-linear simulation research platform and the hardware test platform will be established. The fault experimental prototype of stator windings including inter-phase short circuit of stato
