摘要
建立了机械式离心调速器系统的动力学方程,求出了系统的平衡点。利用系统的相图分析了给定参数下自治系统及非自治系统的运动状态,用Poincaré映射图分析了非自治系统混沌的形成过程。利用线性反馈反控制方法实现了自治系统及非自治系统混沌的反控制,将自治系统及非自治系统的周期运动利用适当的控制强度反控制到混沌运动轨道。
The dynamics equation of mechanical centrifugal governor system was established, and the equilibrium point of the system was given out in this paper. Using the phase portrait of system, the motion status of autonomous and non-autonomous systems under given parameters was analyzed. The chaos forming process of non-autonomous system was analyzed by the use of Poincaré mapping diagram. Utilizing the method of linear feedback anti-control, the anti-control of chaos of autonomous and non-autonomous systems was realized. Using a suitable controlling strength let the periodical movement of autonomous and anti-autonomous chaoses be anti-controlled to the moving track of chaos.
