Active vibration suppression of spacecraft flexible appendages has always been a difficult problem in aerospace attitude maneuver missions. Facing this problem, the component synthesis vibration suppression (CSVS) method is proposed, which can suppress the vibration of the flexible attachment while the spacecraft maneuvers. However, this method has problems such as insufficient anti-interference ability. Therefore, this paper proposes a new control strategy, which combines CSVS with Linear Active Disturbance Rejection Control (LADRC) to further improve the performance of the CSVS method. Specifically, this paper first obtains the CSVS control torque according to the component synthesis design criterion, and applies it to the reference model to obtain the predetermined trajectory. Then, the LADRC controller is used to compensate the interference to ensure that the real trajectory coincides with the reference trajectory. Finally, the stability of the method is proved, and the effectiveness of the method is verified by simulation. The advantage of this method is that it can improve the vibration suppression performance of CSVS method in nonlinear attitude dynamics, and can effectively suppress the vibration amplitude of flexible appendages and improve the attitude control accuracy. Therefore, this control strategy has important practical significance for the control of flexible spacecraft.
