A method for controlling a spacecraft's attitude and reducing vibrations is proposed, which involves utilizing linear active disturbance rejection control (LADRC) for precise tracking and vibration suppression. This method utilizes a dynamic model based on the finite element method and ensures the system is fully controllable. To enhance stability and practicality, an ADRC controller is designed for the system. An extended state observer is used to estimate and compensate for disturbances, resulting in effective attitude tracking and vibration suppression. The theoretical derivation and simulation analysis confirm that the closed-loop system exhibits uniform ultimate stability. Theoretical analysis and simulation results validate the efficacy of the proposed approach in achieving attitude control and vibration suppression.
