Research on adaptive SSDV semi-active vibration control of intelligent cantilever beam based on state observer
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.
