| 摘 要： | 给出了对转子-轴承系统的分岔与混沌等复杂动力学行为进行控制的思想．应用washout-filter状态反馈控制方法进行分岔与混沌控制器的设计，用以改进系统转速变化时转轴响应的分岔与混沌特性．通过调整控制器的参数来影响转子系统的动力学行为，控制其运行的稳定性．数值模拟结果表明，随着转子-轴承系统转速的不断提高，系统的动力学行为会发生较大变化，此时应用washout-filter状态反馈控制方法进行分岔与混沌控制，理论上可起到较好的控制效果．

| Abstract: | This paper presented the idea and method for controlling the complex dynamic behavior of a rotorbearing system, i.e. bifurcation and chaos, and designed a controller by washout-filter feedback method. Modulating the parameters of this controller can control the stability of the rotor system. Numerical simulation result showed that the dynamic behavior changed rapidly when the rotate speed of the rotor-bearing system increased continually, and that the washout-filter feed back method had a good effect on controlling bifurcation and chaos in above condition. |
