Abstract :
This paper presented a second-order sliding mode controller (SOSMC) with the fuzzy control of a magnetic ball suspension system (MBSS). To makes system robustness, the SOSMC controller which improves the chattering phenomenon. This SOSMC controller combines the fuzzy control which rejects the parameter variations and external disturbances. This method utilizes Lyapunov function to guarantee the system asymptotically stable. Finally, we employ the experiments to validate the proposed method.
