Tracking to arbitrary signals in bounded Chen's chaotic system is realized by nonlinear feedback control.Proper feedback form is determined according to the characteristic of system structure,and the nonlinear controller is designed.The Lyapunov direct method is applied to prove that the error signal is asymptotically stable at zero,and all variables in controlled system are bounded.Numerical researches show that the controlled system can track reference signals in arbitrary form,including the output of other chaotic systems.The proposed method is a physically feasible tracking control strategy,and it is also can be used in the synchronization between different chaotic systems.
