The adaptive control of Chen's chaotic system

The control of Chen's chaotic system when its parameters are known a priori or unknown is studied by means of a simple linear state feedback method. W hen the parameters are known a priori, we show the variation range of feedb ack gain; and when the parameters are unknown, an adaptive controller is de signed, which overcomes the drawback that the control is discontinuous in a common adaptive controller. Finally the simulation results vertify the eff ectiveness of our proposed method.
