Distributed adaptive vibration suppression control method of large solar panels for satellites based on Lyapunov theory
A distributed adaptive vibration suppression control method was investigated to effectively suppress the on-orbit vibration of large flexible satellite panels. Considering the influence of actuator and sensor installation position on the control effect, a complete distributed adaptive controller was designed based on Lyapunov theory by analyzing the coupling effect of vibration and output force between adjacent sub-modules. The simulation results show that the vibration suppression time of the proposed distributed control method is reduced by 40% compared with the distributed control method based on LQR control method and 50% compared with the centralized control method under the condition of continuous external interference. Furthermore, the proposed control method has an improved on-orbit vibration suppression effect and is of great significance for the stable operation of the satellite.
