| 摘 要： | 研究了Chen系统的混沌同步问题,提出了线性和非线性两种参数可调节的自适应同步设计方法。设计出使两个相同结构的Chen系统渐近同步的自适应控制器,其参数调节律由Lyapu nov稳定性理论来确定。最后进行数字仿真,仿真结果表明了这两种方法的有效性和实用性。

| Abstract: | This paper addresses the adaptive synchronization and parameter identification problem of two Chen systems with unknown system parameters.The line design methods of adaptive synchronization and the noline design methods of adaptive synchronization are discussed.Two adaptive controllers which can make the states of two identical Chen chaotic system asymptotically synchronization is developed and the adaptation laws for the parameters are given by Lyapunov stability theory.Finally,numerical simulations is carried out;the simulation results show that the design method has good performance. |
