一类连续系统的混沌反控制

针对一类含有复杂动力学行为的连续系统,提出了直接延迟反馈实现混沌的反控制方法。直接延迟反馈方法是将连续系统的当前状态与延迟状态的差信号按一定比例反馈回系统,并选择适当的反馈增益和延迟时间,使处于系统演化过程中的某条稳定的周期轨道呈现出混沌运动。该方法的计算过程和实际的函数控制形式相对简单,且易于实现,能广泛地应用于一般的连续系统的混沌反控制。

Chaos anti-control for a class of continuous systems

Aimed at a class of continuous system with complex dynamics characters, a method of chaos anti-control by direct time delay feedback is put forward. By different signals between current state and delay state of continuous system being feedback to system in definite and choosing an appropriate feedback gain and delay time, Stable periodic orbits in the processes of system evolution can exhibit a variety of chaotic phenomena. The calculation process and the form of function control are simple and easy to realize. The method of chaos anti-control by direct time delay feedback can widely be applied in general continuous system.
