Abstract: Aiming at the eight type position faults of the switched reluctance motor (SRM), the affections of position faults were analyzed in detail, the methods were proposed for fault diagnosis and fault-tolerant control according to the sequence of position single and the relationship between two position singles. Fault-simulation of one position single was performed on the DSP experiment platform, the fault signal was recovered and reconstructed through the normal position signal. The experimental results show that the SRM could keep normal operation after fault-tolerant control during position malfunction, the performance of SRM is improved effectively.

Key words: switched reluctance motor（SRM）; position single; fault diagnosis; fault-tolerant control
