| 摘 要： | 依据Lyapunov稳定理论,结合控制理论中的状态反馈及输出反馈理论,讨论了一种基于自适应状态观测器设计的混沌同步的方法.同时根据持续激励条件讨论了参数估计的收敛性,设计驱动系统的输出及响应系统,使两个同结构的混沌系统状态渐近同步.经过数值仿真证明该方法有效的实现了响应系统与驱动系统的同步并估计出未知参数.

| Abstract: | An adaptive nonlinear state observer-based synchronization approach for unknown parameters chaotic system is discussed.Based on Lyapunov theory,state feedback and output feedback of control theory,we developed an observer-based chaotic synchronization method by setting the output signal artificially.The convergence property of parameter estimation can be guaranteed because the persistent exciting condition is satisfied.Results from the numerical simulations show that the design approach has good performance.It realized the synchronization of response system and drive system.At the same time,the unknown parameters can be estimated. |
