此文件是应用小波分析进行故障检测的matlab程序，包括开路故障，短路故障，飘移故障等。-This file is the application of wavelet analysis for fault detection matlab procedures, including open-circuit fault, short-circuit fault, drift failure.

采用db3小波对信号进行六层分解，可以用作容错故障检测的源程序，我做的小论文就用的这个程序，没有错误-Using six db3 wavelet decomposition of the signal can be used as fault tolerance fault detection of the source, I made a small paper on the use of this program, no errors
