Abstract

Uncertain system parameter identification and self-adaptive synchronization of a class time-delay chaotic systems were proposed. Based on the Lyapunov-krasovskii extensive functional theory, lag synchronization controller and adaptive law of parameters were designed respectively. The simulation with system showed that system synchronization was satisfied and the unknown parameters could be estimated ideally. Experiment results also indicated that this scheme had universality and feasibility in actual applications.
