| 摘要: |
| 在空间绳网的绳系组合体拖曳变轨运动控制中，系绳张力控制策略需要有一套卷扬机构及张力检测控制装置，将增加机构的质量、复杂度和成本，并降低操作可靠性。提出仅利用拖船飞行器上的三轴正交喷嘴控制策略，可同时实现拖曳离轨中的相对运动控制和系统质心的轨道控制，而系绳张力只作为约束，推导了组合体拖曳离轨的三维空间运动动力学模型，给出了一种准霍曼拖曳离轨控制方法，完成了同步轨道废弃目标拖曳离轨方案的初步可行性仿真验证，并给出了拖曳过程的喷气力、燃料消耗量指标，可供空间绳网研究参考。 |

| Abstract: |
| For the motion control of tug deorbit of a tether combined system of rope net in space, tether tension control needs a set of windlass, tension force measurement and control, which will increase the weight, complexity and cost, and decrease operation reliability It has been put forward that the 3-axis orthogonal nozzles fixed in tug vehicle can be used to simultaneously realize relative motion control between tug boat and target, and centre-of-mass control of system orbital motion, but tether tension is only restricted, the three dimensional space motion dynamic model of combined system has been deduced, a quasi-Hohmann tug deorbit method has been given and verified to be feasible by numerical simulation with an example of geostationary tug deorbit, and jet force and fuel consumption has been given, which may be referential for the research of space net |
