Double Fault Parameters Estimation of Motor Based on Four-Order Cumulate of MUSIC

Abstract:

In this thesis, fault characteristic frequency can not be accurately detected if they are drowned by noise. A novel method which is Multiple Signal Classification (MUSIC) based on four-order cumulate is provided to diagnose motor broken rotor bars and stator winding inter-turn short circuit. Because four-order accumulation is able to depress noise meanwhile fault information can be obtained accurately through this way presented even with small samples. Simulation results shown that the method were higher in resolution of frequency, more accurately in fault detection and less in computational complexity.
