Abstract :
A module is the basic control unit of EMS (electromagnetic suspension) type low speed maglev train. The dynamic model of module suspension system, a nonlinear MIMO coupling system, is developed by using Lagrange-Maxwell formulation in terms of energy. The module suspension system contains significant parameter uncertainties, unmodelling dynamics and motional coupling. So a decoupled sliding mode controller, designed by the method of control hierarchy, is employed. The simulation results show that the proposed controller has strong robustness and can effectually solve the coupling problem of the module suspension system
