| Abstract: | An analog circuit diagnosis method based on electromagnetism-like mechanism algorithm was proposed for characteristics of the analog circuit.Firstly,fault features are extracted by using wavelet packet.Then,feature vectors are input to the BP neural network optimized by using electromagnetism-like mechanism algorithm.The method avoids parameters prematurely trapped in local optima,improves the classification capabilities neural network.The simulation and experiment results demonstrate the effectiveness of the proposed method. |
