摘要
基于自适应控制策略和Lyapunov稳定性理论,在参数未知的情况下,讨论了超混沌Qi系统与超混沌Chen系统的异结构同步、设计控制器和参数估计率,实现了两个具有不同结构的超混沌系统的同步,方法简单有效,易于实现,理论分析和数值仿真的结果均证明了该方法的可行性,且该方法可以用来实现其他的超混沌系统的同步.
Based on the adaptive control strategy and the Lyapunov stability theorem, this article discusses the problem on the synchronization of the hyperchaotic Qi system and the hyperchaotic Chen system and designs an adaptive controller and a parameter estimation update law which are derived to make the two hyperchaotic systems synchronized with different structures. The method is simple and easy to achieve, and the synchronization approach is proved feasible through theoretical analysis and numerical simulations. This method can be applied to the synchronization of other hyperehaotic systems.
