Lag synchronization of a class of chaotic systems with unknown parameters. (English) Zbl 1176.34097

Nonlinear Dyn. 57, No. 1-2, 107-112 (2009).
Summary: Research on chaos synchronization of dynamical systems has been largely reported in literature. However, synchronization of different structure-uncertain dynamical systems-has received less attention. This paper addresses synchronization of a class of time-delay chaotic systems containing uncertain parameters. A unified scheme is established for synchronization between two strictly different time-delay uncertain chaotic systems. The synchronization is successfully achieved by designing an adaptive controller with the estimates of the unknown parameters and the nonlinear feedback gain. The result is rigorously proved by the Lyapunov stability theorem. Moreover, we illustrate the application of the proposed scheme by numerical simulation, which demonstrates the effectiveness and feasibility of the proposed synchronization method.
