混沌系统的全局指数吸引集在混沌的控制和同步之中起着非常重要的作用.给出了一个五维混沌系统的模型,然后借助一个适当的Lyapunov函数和最优化理论,研究了这个混沌系统的全局指数吸引集,得到了它的五维椭球全局指数吸引集.最后,通过了计算机模拟,数值模拟验证了计算理论的可行性.
This paper studied globally exponentially attractive set of a chaotic system.The globally exponentially attractive set of this system is investigated via constructing a Lyapunov function and optimation theory. A five dimensional ellipsoidal globally exponentially attractive set is derived, and numerical simulations are presented to show the effectiveness of the proposed scheme.
