The control scheme as networked control systems was proposed for the suspension system of maglev train. First, a mathematical model of the suspension system with network-induced time delay was presented. Then, in the control arithmetic, the knowledge of the plant dynamics was used to compensate the random network-induced time delay and the sufficient conditions for bound on sampling period of asymptotic stability was given. The single module plant of suspension system was established Simulation and experimentation show that the model-based control algorithm is effective.
