为了抑制磁悬浮飞轮的振动,分析了磁悬浮飞轮的振动源。针对磁悬浮飞轮最主要的振动源-不平衡振动,给出了一种基于TMS320C6713B+FPGA数字控制器的磁悬浮飞轮主动振动控制实现方案。介绍了所采用的主动振动控制方法、数字控制器的硬件组成和功能原理,并讨论了DSP中主动振动控制算法的实现和FPGA中多任务管理及外设控制等。实验结果显示,采用本方法进行主动振动控制后,磁悬浮飞轮的不平衡振动衰减至3.2%,表明本实现方案对飞轮转子不平衡振动取得了很好的抑制效果,对于增加磁悬浮飞轮姿态控制的稳定性,提高对地观测分辨率具有重要意义与应用价值。

In order to eliminate the vibration of Magnetically Suspended Flywheel（MSFW）, the disturbing sources of MSFW are analyzed. Aimed at the suppression of main disturbing sources, the unbalance vibration, a new active vibration system based on TMS320C6713B＋FPGA digital controller is presented. The active vibration control method, hardware constitution and functions of digital controller are discussed. The implement of control method in DSP, the organization of multi tasks in FPGA and the control of peripheral devices are provided. The experimental results demonstrate that the unbalance vibration has been reduced to 3.2% by proposed system, which shows this system can eliminate the unbalance vibration of MSFW significantly and has great significance and value for increasing the stability of attitude control and for improving the resolution of earth observation.
