Abstract

Auxiliary inverter is one of the most important electrical equipments of metro vehicle; its complex structure causes various faults frequently. In this paper, the fundamental of the Affinity Propagation algorithm is introduced, and its application on fault diagnosis of metro vehicle auxiliary inverter is studied. Fault signals including voltage frequency variation, pulse transient, and power interruption are simulated by using the MATLAB software; clustering center matrix is calculated on the basis of AP algorithm, and the fault samples are classified by calculating the similarity degree between samples and clustering center. The simulation results show that the AP algorithm without initial clustering center can be used in the field of fault diagnosis, and even has better results than FCM algorithm.
