文摘

This method can detect impulsive fault signatures from strong noises environment. This scheme has low computation complexity and it has a recursive form. It is a linear model suitable for on-line fault detection problem. It incorporates both the frequency and phase information of the vibration signal. The enhanced performance is verified in rotating machinery fault detection.
