An active fault tolerant controller based on switch strategy is designed, for sensor fault issues of the networked control system of maglev train which has random induced time-delay. First, the model considering induced time-delay of the networked suspension control system is established. Then, state-observer for the networked suspension control system is designed using the input of suspension interspace. When sensor faults happen, by switching to the state feedback loop of observer, the stability of system can be kept. Finally, simulation results indicate that the strategy is effective on maglev train.
