摘　　要：半主动振动控制因其不需精确的结构模型就能实现较好的振动控制效果,以航天器上使用的某种轻质复合材料制作的智能悬臂梁结构件为载体,设计一种基于状态观测器的自适应SSDV半主动控制方法对其进行振动控制研究,取得了较好的控制效果,状态观测器观测值误差在1%之内,一阶振动幅值减少了75.24%。这为航天器上柔性化和低刚度的悬臂结构件的振动控制提供一种有效可行的参考方法。Semi-active vibration control can achieve a better vibration control effect without an accurate structural model.An intelligent cantilever structure is made from a lightweight composite material used on spacecraft.An adaptive SSDV semi-active control method based on state observer is designed to study the vibration control of intelligent cantilever beam,and a good control effect is achieved.The observation error of the state observer is within 1%,and the first-order vibration amplitude is reduced by 75.24%.This paper provides an effective and feasible method for vibration control of cantilever structures with flexibility and low stiffness on spacecraft.
