Abstract
This paper considers trajectory tracking control for a one-degree of freedom (DoF) manipulator system driven by pneumatic artificial muscles. A switched sliding mode controller is accordingly designed. In the proposed scheme, a novel extended state observer based on a generalized super-twisting algorithm is first designed to deal with internal uncertainties and external disturbances in the one-DoF manipulator system. Second, the finite time convergence of the closed-loop system with the proposed sliding mode technique is analyzed. Lastly, some experimental results are presented to show the validity and advantages of the proposed approach.
