Probabilistic Entropy EMD Thresholding for Periodic Fault Signal Enhancement in Rotating Machine
Since the slight fault feature of incipient fault is usually polluted by heavy background noise, it is difficult to extract the weak feature signal in rotating machine. As an adaptive decomposing technique, empirical mode decomposition (EMD) based denoising methods have a good effect on the feature...
