Abstract

　　The research of chaotic system is carryied out broadly at home and abroad, and how to get fine effect from the controlling of chaotic system is much more important. This paper discusses a design of method of an adaptive synchronization for the uncertain chaotic system with unknown parameters. An adaptive controller which can make the states of two identical chaotic systems asymptotically synchronized is developed and the tunned laws for the parameters are defined by Lyapunov stability theory. Finally, numerical simulations are carried out, and the results show that the design method has efficiency and applicability.

Keywords: Uncertain chaotic system; Chaotic synchronization; Adaptive controller; Parameters identification
