摘要
分析Lorenz系统的非线性动力学行为的稳定特性,提出一个双延迟反馈控制器,采用双延迟反馈控制方法对Lorenz系统的混沌行为进行了控制,并对混沌控制过程进行了理论分析与数值仿真.通过对受控系统最大Lyapunov指数的计算,能够预知受控的Lorenz混沌系统被控制到何种状态.并实时改变延迟时间,进行动态控制,丰富了Lorenz混沌系统的应用方法.
The nonlinear dynamics characteristics and stability of the Lorenz system are analyzed.A method for designing a two-delayed feedback controller is put forward.The chaotic behaviors of the Lorenz system are controlled by chaotic control methods which are called two-delayed feedback control.Theories of these methods are analyzed and simulated numerically.By calculating the max Lyapunov exponent of the system,the chaotic systems can be predicted to control in some states.With the change of controlled delay tim...
