摘要
以超混沌liu系统为研究对象,采用基于状态观测器的理论来构造观测器,实现了超混沌liu系统的反同步。同时根据非线性反馈的思想设计出一个控制器来实现该系统在不同初始值条件下的反同步,并通过李雅普诺夫稳定性定理证明了控制器的合理性。利用Matlab对两种反同步方法进行数值仿真,证明了其可行性和有效性。
Taking hyperchaotic liu system as the object of study,the state observation theory was based to construct appropriate observers to achieve anti-synchronization of hyperchaos liu system;meanwhile,basing on the nonlinear feedback,a suitable controller to realize anti-synchronization of the system under the condition with different initial values was designed and its rationality was proved by Lyapunov stability theorem.Simula-ting these two synchronization methods with Matlab prove their feasibility and effectiveness.
