Abstract:
This paper presents a new Terminal sliding mode control surface for a class of s econdorder nonlinear uncertain systems to eliminate the singularity problem in conventional terminal sliding mode controls, so that the system can be guarantee d to converge to an equilibrium point from any initial state within a finite tim e in the phase of sliding mode motion. To deal with the upper bounds of uncertai nties such as systematic parameter perturbations and external disturbances, an a daptive nonsingular Terminal sliding mode (NTSM) control with parametric estim a tion for uncertain upper bounds was derived using Lyapunov stability theory .The simulation results of an example are investigated to show nonsingularity term inal sliding mode can elimination the singularity,and also show the feasibility and the effectiveness of the selfadaptive method.
