进化策略在控制混沌中的应用

Application of Evolution Strategies in Controlling Chaos

将模拟自然界生物进化过程的进化策略用于控制混沌，提出了一种以改进后的混合进化策略指引混沌轨道的新方法．使混沌系统在微小扰动作用下，以较短的时间从某一给定的初始点到达要求的不动点附近区域，达到加快控制混沌的目的．对Ｈéｎｏｎ 映象进行了数值仿真。

Evolution Strategies (ES) simulating the evolutionary mechanism of nature are used for controlling chaos. A new method of directing orbits of chaotic dynamical systems is presented based on improved hybrid ES. The chaotic dynamical systems can rapidly reach a small region about a desired target point from a source point by applying tiny pertubations in a short time. The Hénon map is used to demonstrate the effects of the proposed method. The numerical simulation result shows that the method is effective.
