Robust finite time synchronization of chaotic systems

Abstract

In this paper, a robust finite time fast sliding mode controller is presented fo r a class of chaotic synchronization. Using the fast sliding mode controller, ma ny chaotic systems can achieve synchronization with identical response system th rough state transformation, and Chen's system and hyperchaos system of 4th_order cellular neural network are used to demonstrate the obtained results. The resul ts show that the controller possesses the advantage of fast response and robustn ess.
