Controlling and tracking hyperchaotic Rossler system via active backstepping design

This paper presents a novel active backstepping control approach for controlling hyperchaotic Rossler system to a steady state as well as tracking of any desire trajectory to be achieved in a systematic way. The proposed method is a systematic design approach and consists in a recursive procedure that interlaces the choice of a Lyapunov function with the design of active control. Numerical results show that the controller is singularity free and the closed-loop system is stable globally. Especially, the main feature of this technique is that it gives the flexibility to construct a control law. Finally, numerical experiments verify the feasibility and effectiveness of the proposed control technique. (c) 2005 Elsevier Ltd. All rights reserved.
