摘要
针对一类新的超混沌系统,提出了一种追踪控制方案,利用Lyapunov方法证明了受控系统可使其状态输出指数收敛到任意给定的参考信号,实现同步.讨论了一个四阶超混沌系统的自同步及与Lorenz-Stenflo系统的异结构同步问题,数值仿真进一步验证该方法的有效性.
A tracking control method was proposed for hyperchaotic system. It is proved by means of Lyapunov function that this method could make the control system approach to any reference signal. This paper investigates the self-synchronization of a new fourth-order hyperchaotic system as well as the synchronization between the Lorenz-stenflo system and the new fourth-order hyperchaotic system. In the end,numerical simulations are given to illustrate the effectiveness of the proposed method.
