摘要 在线消除转子系统的振动对保证旋转机械的可靠和高效运行是至关重要的。在转子振动控制初期，需要一个试探性的控制力，该力可能会使系统振动加剧或减小，这取决于控制力与原激振力相位之间的关系。为此本研究在转子系统动力学及电磁力可控特性分析的基础上对控制力相位进行区域划分，建立系统寻优控制模型并提出具体寻优策略；采用有限元分析的方法获取工作转速下转子系统理论滞后角，初步确定控制力相位；以此相位值作为寻优参数起始值，按照既定寻优策略实现转子自动平衡控制，并确保控制全过程转子振幅不大于初始不平衡故障振幅；最后建立实验台并对算法进行实验验证，结果表明该方法是有效的。

Abstract: It is vital important for ensuring reliable and efficient rotating machinery operation to eliminate the vibration of rotor system online. Early in the rotor vibration control, a tentative control force is needed. The force might make the system vibration aggravate or reduce, which depends on the relationship between control force phase and excitation vibration force phase. So, depending on the analytic of the rotor system dynamics and electromagnetic force controllable characteristics, the regional division of the phase of control force was done. And the control model was built and some specific optimization strategy was proposed. The finite element analysis method was used to attain the system theory lagging angle under working speed. The phase value of control is determined and the phase is used as the initial value of optimal parameters, and ensuring the vibration amplitude is not more than the initial fault amplitude of rotor during control. Finally the test equipment was established and the experimental results show the algorithm is effective.
