Abstract: 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.
