Parameters Estimation and Adaptive Synchronization of Chaotic Systems with Adaptive Parameters Perturbation

This paper investigates the problem of parameters estimation and adaptive synchronization of chaotic systems with adaptive parameters perturbation. Based on Lyapunov stability theory, the general expression of the suitable adaptive synchronization controller is developed. In comparison with those of existing parameters perturbation methods, the parameters perturbation are given by adaptive laws in this paper. Numerical simulations are also given to show the effectiveness of the proposed method.
