N2 - Aiming at a vibration control method in transfer of space tether tugging system, an input shaping control strategy suitable for rope combination is proposed, which is applied to suppress vibration of flexible accessories during satellite orbit transfer. For the spacecraft with flexible appendages, the modal coordinate method is applied to establish the dynamic model based on the Lagrange principle. Then the basic principle and the basic design of the input shaper to suppress the vibration are introduced. An input shaper is designed for the flexible appendage of the mission satellite, then validate the method by simulation. The results show that the coordinated control method of the attitude maneuver of the system can achieve the safe and stable control of the attitude. Considering the flexible accessories, the rail control thrust, attitude control torque and tether tension will disturb the flexible accessories. After input shaper for the above control variables, the vibration of flexible appendages can be effectively avoided and the modal coordinates can be rapidly converged.
