摘 要: In this paper, we focus on improving the rotational accuracy of the magnetic bearing under the consideration of the unbalance force of the spindle and the unbalanced magnetic pull of the motor. First, the vibrations of the spindle are analyzed. Next, in order to suppress the vibrations of the spindle, a combined repetitive control method is proposed, which includes a space domain repetitive compensator and a time domain repetitive compensator. Furthermore, the experimental results show that the proposed method is effective for suppressing the vibrations of the spindle and the rotational accuracy is improved from 301.2 to 21.9 nm at 2880 min{sup}(-1).

本文重点研究在考虑主轴不平衡力和电机磁力不平衡牵引力的情况下,提高磁轴承的旋转精度。首先分析了主轴的振动情况,接着提出一种组合式重复控制方法,该方法包含空间域重复补偿器和时间域重复补偿器,以抑制主轴振动。实验结果表明,所提出的控制方法有效抑制了主轴振动,使旋转精度从2880 min⁻¹时的301.2 nm提升至21.9 nm。
