Distributed Vibration Control of Large Satellite Solar Panels

The vibration of large satellite solar panels will seriously affect the attitude stability and pointing accuracy of the satellite, and may even cause structural damage through the coupling with the central rigid body. Consequently, it is of great realistic significance to control the vibration of satellite solar panels. The main contents of this study include: Firstly, the multiple-subsystems model is founded based on the finite element method. Secondly, according to the established model, the distributed vibration control algorithm is designed based on algebraic graph theory and consensus theory, and the stability of the closed-loop system is analyzed. Finally, simulation experiments are designed to verify the effectiveness and robustness of the algorithm. The simulation results show that the distributed vibration control algorithm developed on consensus theory can not only effectively suppress the vibration of solar panels and improve the dynamic performance of the system, but also has good robustness.
