Abstract :
In this paper, a variable structure control scheme is proposed for second-order nonlinear uncertain systems. By using a function augmented sliding hyperplane, it is guaranteed that the output tracking error converges to zero infinite time which can be set arbitrarily. The proposed scheme eliminates the reaching phase problem so that the closed-loop system always shows the invariance property to parameter uncertainties. Furthermore, it has no singularity and does not show a periodic motion
