Abstract—This paper presents regulation and tracking control design for a magnetic levitation system (Maglev). First, the nonlinear dynamic model of magnetic levitation system was built. Second, a sliding mode control (SMC) is constructed to compensate the uncertainties occurring in the magnetic levitation system. The control gains were generated mainly by experimental method. Next, a composite controller consisting of a PID plus a SMC algorithm was proposed to enhance overall tracking performance. The effectiveness of controllers was verified through experiment results.
