| Other Abstract | The main research contents of this paper include the research and design of space tether tension control system, the vibration suppression strategy along the tether direction and the tension control strategy in the recovery process during the assembly setting process after the space tether capture system captures the target, and the design and development of the tension control experimental platform for ground tension control test. The main work of this paper is as follows. (1) The dynamic equation of space tethered capture system is studied. A dynamic model for towing recovery of space tethered composite system over circular orbit is established. (2) The design requirements of tension control mechanism are studied, and a prototype of double closed-loop tension control mechanism based on position inner loop is designed. (3) The minimum principle is studied to solve the optimal control of vibration along the rope direction. The optimal control strategy simulated by MATLAB can achieve the vibration suppression along the rope direction very well. Secondly, the tension control in the recovery process of tie rope is studied. (4) The tension tracking experimental platform of tension control mechanism and the ground test platform of vibration and recovery process along the rope direction are studied and designed. The constant tension and dynamic tension tracking experiments and the ground simulation experiments of rope tension control are carried out on the test platform respectively. (5) The tracking performance of tension control mechanism and the tension control during the process of capturing the target star along the direction of the tether are summarized, and the future work is prospected. |
