摘要
将模糊集理论引用到故障诊断方法中,通过对因果矩阵推导、诊断结果的确定原则分析、隶属度函数确定方式的论述,推导出面向故障诊断的模糊理论方法,并将该方法应用到某型机机载雷达故障诊断过程中。结合对某型机机载雷达故障诊断分析,证明了该方法的有效性。
The paper introduces a fault diagnosis method by using fuzzy set theory. Based on analysising reason-reasult matirx, fault diagnosis reasult judgement method, membership value reasoning function,the fuzzy set fault diagnosis method has been builted. Also the paper give an example by analysising centain aircraft radar' fault diagnosis. The result shows up that the fuzzy set method used in fault diagnosis is avialiable.
