Summary:The faults of sensors occurred in Maglev train's suspension system reduce the running performance even disable the suspension system. Especially in the high-speed Maglev train, the loss is unpredictable. This paper focuses on the fault tolerant control problem of the suspension system. And the methods of control strategy reconstruction and state estimator were adopted. Based on the model of the simplified suspension system, the reconstructed controller and state estimator were designed. Furthermore, the simulated analysis for the static and dynamic levitation process was done by the software of Simulink. It is clearly observed that the FTC scheme can remain the static and dynamic performance in conformity with the original system. At last, the new FTC index used to judge the FTC problem of the unstable system is brought forwarded
