| 摘 要： | 讨论基于模糊规则的模糊诊断方法中隶属函数的选择问题，以同步电机的匝间线圈故障检测为例，将逆电流和逆电压作为模糊故障检测的两个输入变量，以同步电机的故障代码值为输出变量，分别采用三角形、梯形和高斯型三种隶属函数进行模拟，从模拟结果分析得出在一般电气设备的模糊故障诊断中，采用三角形隶属函数进行模糊故障诊断的准确度优于使用梯形和高斯形隶属度函数。

| Abstract: | The effectiveness of fuzzy fault diagnosis has been analyzed through simulation studies with triangular trapezoidal and Gaussian membership functions and results are compared. It is observed from the results that th performance of fuzzy fault diagnosis with triangular membership function is better than trapezoidal and Gaussian membership functions. |
