摘要
借助Lyapunov稳定性理论,研究非线性参数不确定的超Liu混沌系统的自适应同步问题,构造自适应控制器,设计参数辨识结构,探讨非线性参数不确定的超Liu混沌系统产生自适应同步所需的充分条件,采用4阶龙格-库塔方法进行仿真,验证其方法具有有效性.
The adaptive synchronization of hyper Liu chaotic systems is studied based on uncertain nonlinear parameter by the Lyapunov stability theory. An adaptive controller is constructed and a parameter identification is designed. Sufficient conditions for the adaptive synchronization of hyper Liu chaotic systems with uncertain nonlinear parameters are discussed. And the fourth-order Runge-Kutta method is simulated. It is proved that the method is effective.
