摘要

This paper addresses the sliding mode switching control problem based on disturbance observer for an uncertain robot manipulator system. To enhance the robustness and the anti-disturbance capability of the system control algorithm, the manipulator's switching model is composed of two parts: a slide mode controller and a disturbance observer. Based on multiple Lyapunov stability theorem and average dwell-time method, it is proved that the proposed control scheme can guarantee the global stability and robustness of the resulting closed-loop system of robot manipulators system. The application of the proposed switching control scheme with disturbance observer to a robot manipulator shows satisfactory tracking error performance than in the case of switching control strategy without disturbance observer.
