| Abstract |
This paper presents a sliding mode observer and controller for the state estimation and the dynamic stabilization of the magnetic levitation systems. The proposed sliding mode observer is constructed by means of Lyapunov stability theorem to decrease the observer error, and the sliding mode controller is designed by a linear combination of the equivalent and nonlinear control input for the estimated states. The feasibilities of the suggested design method are illustrated with the simulation results. |
