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。
In towing orbital motion control of rope combination of space ropes, the tether tension control strategy needs a winch mechanism and tension detection control device, which will increase the quality, complexity and cost of the mechanism and reduce the operation reliability. It is proposed that only the control strategy of the three-axis orthogonal nozzle on a tug aircraft can realize the relative motion control and the orbital control of the system centroid at the same time, and the tether tension is only used as the constraint, the three-dimensional Space kinetic model, a kind of quasi-Hohmann towing off-orbit control method is given, and the preliminary feasibility simulation of the towing off-orbit scheme of the synchronous orbit rejection target is completed. The jet force and fuel consumption Indicators, for space rope network research reference.
