Aiming at the problems of fault diagnosis for rotating machinery, this paper proposed a fault diagnosis method combining minimum entropy deconvolution (MED) with fruit fly optimization algorithm (FOA). In the MED method, the objective function method (OFM) is used to find the set of filter coefficients under the condition of maximal kurtosis. Given that the filter coefficients obtained by OFM are...
The issue of test node selection for the fault diagnosis of analog circuit is studied in this paper. The formula of computing the ambiguity entropy of the test node is defined and a new algorithm of selecting test node based on the ambiguity entropy is presented. The practical application proves that the algorithm can cut the test node to the bone and enhances the correctness and real time of fault...
