摘要
研究了不确定Chen系统的自适应同步和参数识别,讨论了一种参数可调节的自适应同步设计方法。设计出了可以使两个同结构的Chen系统状态渐近同步的自适应控制器,其参数调节律由Lyapunov稳定性理论来确定。最后进行数字仿真,结果表明了这种方法的有效性和实用性。
Author addresses the adaptive synchronization and parameter identification problem of two Chen systems with unknown system parameters. A design method of adaptive synchronization is discussed . An adaptive controller 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.
