The stability control for magnetic levitation system is a considerable and hard scientific issue because of highly nonlinearity and instability.This paper mainly focuses on the stability control for the levitated positioning and attitude of the magnetic levitation system.For the nonlinear magnetic levitation system model,the output feedback linearization method is employed to derive a global linearization error model.To stabilize this error model,the backstepping method is used to design the stability controller.Simulations show that the magnetic levitation system can be stabilized and track desired signals quickly under controlled by the proposed control scheme.
