| 摘 要： | 介绍了一种基于双观测器的故障隔离方法。通过设计一个不受敏感器故障累积效应影响的特殊观测器与另一个常规观测器联合起来检测和隔离传感器及执行机构的故障。对双观测器的故障诊断方法进行了改进,并将改进算法应用于无刷直流电机闭环系统的故障检测和隔离。通过仿真结果可知,对于无刷电机典型的输入、输出型故障,用该方法可以准确定位和隔离。

| Abstract: | The fault diagnosis method based on double observers is introduced and it is applied to the fault diagnosis of brushless DC motor closed loop system. Through simulation, we can draw a conclusion that the method proposed in this paper can detect and isolate the typical input and output faults of brushless DC motor closed loop system correctly. |
