Parameter Identification and Control of a Chaotic System

This paper applies the idea of observer to the identification of unknown parameters in the systems and studies the identification of unknown parameters of chaotic systems. Computer simulations show that when the unknown parameter is a constant or slowly time-varying signal, this method can be utilized to arrive at good identifying results. The paper also analyzes the problem of identification and control, and then presents an improved scheme for chaotic control. Simulations have been conducted to demonstrate the effectiveness of the proposed method.
