摘　　要：本文首先论述了有源磁悬浮在国内外的发展状况和趋势,接着论述采用有源磁悬浮的目的和对有源磁悬浮的要求,并对时分式直流反馈有源磁悬浮的工作原理、磁悬浮元件、磁悬浮系统的稳定性、时分模拟开关以及对反馈回路的方案进行了分析。实验结果表明,有源磁悬浮应用于陀螺加速度计对仪表精度的提高起到了关键性作用。This paper couers the development and tendency of the active magnetic suspension at home and abroad,and then describes the purpose and requirements of using the active magnetic and suspension,components its stability of the active magnetic suspension, the operating principle of a time-sharing DC feed-back active magnetic suspension,a time- sharing analogue switch and the scheme of the feed-back circuit are also analyzed. The result of experiment has proved that the active magnetic suspension is very important to improve accuracy of instrument.
