... on the grey wolf optimizer (GWO) algorithm for rolling bearing fault diagnosis. The periodical stochastic resonance (PSR) model can independently adjust the system parameters and effectively avoid output saturation. The GWO algorithm is introduced to optimize the PSR model parameters to achieve adaptive...

... Morlet wavelet, Figs. 3a 3b depict the scale-kurtosis distribution of the WT using Morlet and Laplace wavelets, respectively, for different bearing conditions. The comparison of the two figures indicates the high sensitivity of the Laplace wavelet over the Morlet wavelet for bearing fault diagnosis...
