通过理论分析与数值仿真,分别实现了一类超混沌系统的线性与非线性反馈控制耦合同步.利用超混沌系统的最大Lyapunov指数确定反馈控制系数需满足的取值范围,实现线性耦合同步.对于非线性耦合同步,则是基于对Lyapunov方法的理论讨论,给出超混沌系统在全局范围内实现同步的充分条件.
Through theoretical analysis and numerical simulation,this paper achieves the linear and non-linear feedback control coupling synchronization of a hyperchaos system respectively.Through the largest Lyapunov exponent of the hyperchaos system,the value range of feedback control coefficient is determined to achieve linear coupling synchronization;for nonlinear coupling synchronization,it is based on the theoretical discussion of Lyapunov method that the sufficient condition to achieve synchronization in the gl...
