This paper presents a nonlinear control technique, feedback linearization, for an electromagnetic suspension (EMS) system which is a nonlinear system. It is shown that the EMS system is feedback linearizable as it satisfies the required conditions. For the EMS system, feedback linearization technique is used to design stabilization control and tracking control. For the tracking control a random sinusoidal trajectory is taken as the reference signal. Also, these results are compared with that obtained using the standard linear state-feedback controller whose design is based on a linearized model of the plant obtained by small perturbations of the plant around an operating point.
