摘　　要：针对开关磁阻电机(SRM)位置信号可能出现的8种故障情况,对各故障可能产生的影响进行了分析,根据位置信号的脉冲时序及两路位置信号之间的相位关系,提出了有效的位置信号故障诊断与容错控制的方法;同时,在DSP实验平台上模拟了一路位置信号出现故障的情况,利用正常的一路位置信号实现了对故障信号的恢复与重构。研究结果表明,经容错控制后的SRM可在故障出现后继续保持正常运转,SRM的性能得到了有效地提高。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 relation-ship 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.
