Research of nonlinear control for maglev train

The model of maglev train suspension system is established. For the nonlinearization of the model, feedback linearization techniques are applied. A simple P-controller and a nonlinear compensator are designed after the input-status linearization of the system is achieved. The simulation result is derived, based on which, a digital experiment is performed. A comparison is made between the simulation results and experiment results, the latter of which shows the feedback linearization techniques can resolve the control problem of maglev train's nonlinear model.
