挠性卫星振动抑制的变结构主动控制方案及实验研究

Variable Structure Active Vibration Control and Experiment Research for Flexible SatelliteS

文章从工程角度出发，以具有挠性太阳帆板的卫星为背景，着重研究了挠性空间结构的低阶模型变结构控制方案。针对卫星的“飞轮—喷气”执行机构工作模式设计了算法简单的变结构控制律，并基于单轴气浮台全物理仿真系统成功地进行了国内首次挠性结构振动主动控制实验，取得了显著的控制效果。

In this paper a variable structure active control scheme is studied in view of engineering for flexible space structure such as satellites with salar arrays. According to the wheel -jet actuator working mode abapted by current satellites, a variable structure control law with very simple algorithm and strong robustness is designed. With a physical simulation system based on a single axis air bearing table, the control scheme is successfully realized and verified with a series of experiments for the first time in our country, and many satisfactory results are obtained.
