A novel method based on a fault dictionary that uses entropy as a preprocessor to diagnose faulty behavior in switched current (SI) circuit is presented in the paper. The proposed method uses a data acquisition board to extract the original signal form the output terminals of the circuit-under-tests. These original data are fed to the preprocessors for feature extraction and finds out the entropies...
A novel method for fault diagnosis of analog circuit based on chaos differential evolution wavelet neural networks (CDE-WNN) is proposed in this paper. In order to simplify network architectures and improve its learning accuracy and convergence rate, the architectures and parameters of wavelet neural networks are optimized by chaos differential evolution algorithm in the method. The fault dictionary...
