Sliding Mode Control of Magnetic Levitation Systems Using Hybrid Extended Kalman Filter

This paper presents an approach to control a magnetic levitation system with uncertainty in the dynamics and the measurements. First, Sliding Mode Controller (SMC) is applied to the magnetic levitation system. Then, Hybrid Extended Kalman Filter (HEKF) is used to increase the robustness of the magnetic levitation system to uncertainties. The efficiency of such combined control method is verified by simulation results and performance parameters. Key words : Magnetic levitation system; Sliding mode control; Hybrid extended kalman filter
