摘　　要：为控制磁悬浮飞轮的微振动,以振动力为抑制目标,提出了一种基于陷波器的复合控制方法。通过对磁悬浮飞轮干扰系统的建模,分析了振动力产生的机理,将传感器同频干扰和质量不平衡产生的同频振动力与传感器倍频干扰产生的倍频振动力分别进行抑制,提出抑制同频振动力与倍频振动力的全频复合陷波器控制方法,并通过MATLAB/Simulink仿真进行振动控制效果的验证,转速为209rad/s和628rad/s时分别在0.3s和0.65s后振动力趋近于0N;仿真结果表明,复合陷波器控制方法可以在全频范围内快速抑制同频及倍频振动力。In order to control the micro-vibration of maglev flywheel,by taking the vibration force as the suppression target,a compound control method based on notch filter is proposed.Through the modelling of magnetic levitation flywheel interference system,the mechanism of vibration force is analyzed,and the synchronous vibration force caused by sensor runout,unbalanced vibration force and the frequency-doubling vibration force caused by sensor runout are suppressed respectively.A full-frequency compound notch filter control method for suppressing synchronous vibration force and frequency doubling vibration force is proposed,and the vibration control effect is verified by MATLAB/Simulink simulation.When the rotational speed is 209rad/s and 628rad/s,the vibration force approaches to 0N after 0.3s and 0.65s,respectively.The simulation results show that the synchronous and frequency-doubling vibration force in the full frequency range can be quickly suppressed by using the compound notch filter control method.
