摘要： 从OGY方法的参数微扰混沌控制思想出发，提出了基于线性二次型最优调节器（LQR）的混沌控制方法。以转子转速为微扰控制参数，通过设计最优调节器，使碰摩转子原本的混沌振动稳定到周期等于工作转速周期的轨道上。仿真计算表明，按最优调节器设计的状态反馈比OGY方法获得了更好的控制效果。

Abstract: An approach to controlling chaos with linear-quadratic regulator (LQR) is proposed according to the idea of OGY method, which is based on the linear analysis and control of the dynamics of the system in a Poincare section with parameter perturbation. The chaotic vibration of a rub-impact rotor is controlled to operational periodic one by aped perturbation calculated from LQR. It is showed by numerical simulation that the method based on LQR is more efficient than the OGY method.

Key words: Chaos, LQR, OGY, Rotor, Rub-impact
