Abstract

This paper presents an optimal and robust VSS controller for discrete-time systems. Firstly, a VSS control law is designed, which enables the system state to move into a sliding sector where the closed-loop system is stable. Then optimal control theory is used to design an optimal sliding sector. Finally, the bounded parameter uncertainty is taken into consideration, the robustness of the VSS control system is shown. The simulation of the pendulum control system shows that the VSS controller proposed in this paper is stable and robust to bounded parameter uncertainty
