摘要

Train control system is a typical hybrid system, where the speed and position of train is closely related to the operation safety of high-speed train. A hybrid system model of train movement is proposed to reflect the characteristics of train control system in this paper. For three types of faults in the speed and position system, an improved particle filter algorithm based on hybrid system model is proposed for fault diagnosis. The simulation results indicate that the fault diagnosis method based on hybrid system model is effective for the speed and position system of high-speed train.
