摘要提出一种转子多频振动的在线主动抑制方法，该方法利用电磁作动器向转子施加多个与转子振动频率相匹配的旋转电磁力，通过在线自寻优的方式确定电磁作动器的控制电流相位和幅值，使施加的多个频率成分的旋转电磁力能够削减转子的多频振动幅值，实现转子系统的多频振动在线抑制。首先建立了转子-轴承-电磁作动器系统动力学模型；提出一种转子系统多频振动的主动抑制方法，对该方法的有效性和可行性进行了理论推导；建立了电磁作动器控制电流相位和幅值的寻优模型，提出一种控制电流相位的整周寻优策略；最后搭建实验装置，进行了实验研究，理论推导和实验结果均表明该方法能够实现转子的多个频率成分振动的主动抑制。

Abstract：A approach is proposed for the control of rotor multi-frequency periodic vibration in rotor-bearings system with electromagnetic exciters through self-optimizing control. The control strategies have included arithmetic that optimized the amplitudes and phases of the control signals using an on-line self-optimizing algorithm and apply multiple frequency-matched control force that electromagnetic exciters generate to reduce the measured amplitudes of rotor. The model of rotor-bearings system with electromagnetic exciters is established firstly. An active vibration control scheme for controlling transverse vibration of the rotor due to multi-frequency excitation is designed. And the whole circle search algorithm about the phase of control current is proposed. Finally, the experiments for controlling multi-frequency vibration of the rotor were carried out on the rotor-bearings test rig. The experiment results indicate that the proposed method is effective in reducing rotor vibration arising from multi-frequency force.
