摘要
混沌控制在最近十几年的研究中已经取得了长足的进展,形成了许多比较成熟而且有效的控制技术和方法,如:OGY控制、线性状态空间反馈等 但对于带有未知参数的系统,前面提到的方法常常无法达到预期的控制 通过构造识别函数识别L櫣′s混沌系统的未知参数,然后应用Backsteppingdesign控制L櫣′s混沌吸引子,将L櫣′s混沌吸引子控制到一个稳定的周期轨道。
Great progress has been made in chaos control in the last ten years and some mature and effective controlling techniques such as OGY control and linear condition space feedback have been developed. However, for systems with unknown parameters, the above methods cannot attain the anticipated control. In this paper, we construct an identify function to identify the unknown paramemeters in Lü′s chaotic system and apply the Backstepping design to control the Lü′s chaotic attractor to a stable periodic orbit. We also prove the validity of the control method through numerical simulations.
