Controlling Chen's chaotic attractor using backstepping design based on parameters identification

In this Letter backstepping design is proposed for controlling Chen's chaotic attractor based on parameters identification. The observer is applied to the identification of the unknown parameters of Chen's chaotic system. And on this basis, an efficient backstepping design is developed for controlling Chen's chaotic system. Finally, numerical simulation are provided to show the effectiveness and feasibility of the developed controller design method. (C) 2001 Elsevier Science B.V. All rights reserved.
