| Abstract: | A method of dynamic system fault diagnosis based on wavelet analysis was presented.The simulation model of dynamic system was built in Matlab/Simulink,and MRA theory of wavelet analysis was used to process the output signals,thus,dynamic system fault diagnosis was implemented according to the data processing result.The simulation result shows that the noise in the test data can be eliminated effectively and quick fault diagnosis can be realized with the method. |
