Chattering reduced sliding mode control for a class of chaotic systems

Abstract

This paper presents a sliding mode control scheme for chaotic systems. Finite time stability of the system states is realized by implementing the proposed controller, which is designed on the basis of a nonlinear sliding surface and a new sliding mode reaching law. The new reaching law contributes good control performance in terms of system reaching time and input chattering reduction. Principles for controller parameter selection are given in detail. Simulation results of two controlled chaotic systems are provided to demonstrate effectiveness of the proposed method.
