Fault-tolerant control strategy for the suspension module of EMS High-speed maglev train

The accurate model that is corresponding with the EMS-type High-speed Magnetic-levitation Train is very difficult to be acquired due to the fault. A kind of passive fault-tolerant controller is designed by using simultaneous stabilization theory based on the lapped structure of suspension module. The simulated analysis shows that under the situation that a suspension module in tapped structure totally loses efficacy, and the train can suspend stably still, which ensures the fault-tolerant ability in a stable sense of the system for the fault, improving the working reliability of the high-speed magnetic-levitation train.
