Fault Diagnosis of Rolling Bearings Based on WPE by Wavelet Decomposition and ELM
The fault diagnosis classification method based on wavelet decomposition and weighted permutation entropy (WPE) by the extreme learning machine (ELM) is proposed to address the complexity and non-smoothness of rolling bearing vibration signals. The wavelet decomposition based on ‘db3’ is used to dec...
