Terminal Sliding Mode Control of the Flexible Manipulator

Article Preview

Abstract:

Aimed at the finite-time stabilization problem of a class of flexible manipulators, a stabilization controller based on terminal sliding mode control was proposed in this paper. Firstly, the nonlinear model of flexible manipulators was transformed into linear system through the exact state feedback linearization. Based on the finite time stabilization control method of the linear system, a stabilization controller based on terminal sliding mode control was designed for the flexible manipulators. Furthermore, it was proved that all the states of flexible manipulators could be stabilized to equilibrium in finite time with the proposed controller. The simulation results showed that the performance of the flexible manipulators with the proposed finite-time state feedback controller was effective. At last, the analysis and comparison of the proposed controller and the finite-time state feedback controller were given.
