FAULT FEATURE EXTRATION METHOD BASED ON LCD FUZZY ENTROPY AND MANIFOLD LEARNING

Aiming at the fact that the vibration signal of hydraulic pump would exactly display non-stationary characteristics and fault features hard to extracted,a feature extraction method of hydraulic pump based on LCD（ local characteristic-scale decomposition） fuzzy entropy and manifold learning was propo...
