This paper investigates adaptive synchronization between two noise-perturbed chaotic systems with fully uncertain parameters. Based on Lyapunov stability theory and adaptive control theory, the general expression of suitable nonlinear controller is developed. At the same time, the noise-perturbed update laws of parameters are designed and the synchronization between different unknown chaotic systems is realized. Theoretical analysis and numerical simulation are presented, and the effectiveness and feasibility of the adaptive controllers are verified.
