Active Fault Tolerant Control for Maglev Train against Accelerometer Failure

摘要：

Considering accelerometer failure of single electromagnet suspension system of maglev train, a sensor-fault diagnosis system based on unscented Kalman filter is designed. According to the results of fault detection and diagnosis on line, a improved PID regulator designed off line with tracking differentiators is adopted to tolerate the accelerometer failure. The simulation indicates that the fault diagnosis system designed can detect and localize failures of multi-sensors exactly. In this paper, the effectiveness of the accelerometer-fault control system has been verified on the single electromagnet suspension model of maglev train.
