Abstract

This paper presents a second-order sliding mode position control design for robust stabilization and disturbance rejection of the magnetic ball suspension system. With respect to conventional sliding mode control, the second-order sliding mode technique shows the same properties of robustness to uncertainties of model and external disturbances. The proposed second-order sliding mode control has the continuous control signal that improves the chattering phenomenon. Finally, we employ the experiments to validate the proposed method.
