| 摘 要： | 针对一个电力传动模拟系统利用MATLAB小波工具箱，选用dmey小波作小波母函数，对该模拟系统的正常信号和故障信号进行了多尺度小波分析，通过分析这些小波变换的不同曲线，可以准确地判断出该系统出现了何种故障．可以说小波变换是电力传动系统故障诊断的有效工具．

| Abstract: | Applied MATLAB Wavelat tools box,Selected dmey wavelet as mother wavelet,analyzed normal signals and fault signals using multi-scale wavelct ancalysis on a simulated electric driving system.Overpass analyzed these different curves of wavelet transform,we can make a exact judge that what kind of fault with the system.We can say wavelet transform is the effective tool on detecting of electric driving system fault. |
