混沌吸引子不稳定周期轨道控制方法研究

A new method for controlling over unstable periodic orbits embedded in chaotic attractor is presented. This method first finds out the approximation of unstable equibrium points in chaotic attractor from the system map graph; and then, the nonlinear feedback control is used to achieve the purpose of controlling over chaos. The main characteristic of this method is to exert control actions at any time in the chaotic state without knowing any concrete modes in the chaotic system. In addition, this method is characterized by the very strong ability to resist interference, very fast convergence speed, simple controlling structure, being easy to achieve its structure. The simulation results indicate the effectiveness of this method.
