Fault Diagnosis of Rail Vehicle Suspension Systems by Using GLRT
In this paper, we consider fault detection issue for Rail Vehicle Suspension Systems. The faults considered are the secondary vertical damper fault, the vertical spring fault and sensor failure. A Kalman. lter is applied to generate the residual for fault detection. When there is a detectable fault, the observer sends an alarm signal if the residual evaluation is larger than a prede.ned threshold. The effectiveness of the proposed approach is demonstrated by simulation results for several fault scenarios.
