Terminal Sliding Mode Control Design with Finite-time Convergence

Zhao Yu

Abstract

A finite-time convergence of Terminal sliding mode(TSM)control for a class of SISO nonlinear systems is presented.A design method of terminal sliding surface and control is proposed for the second order nonlinear dynamic systems with external disturbance.It is shown that the system state variables can be driven into each sliding surface and reach the equilibrium point from any point in the sliding mode surface in finite time.Compared with the general terminal sliding mode,it can reach the equilibrium point in shorter time in the sliding mode surface.Simulation results show the validity of the theoretical analysis.
