针对深空探测中应用动量交换系绳辅助进行行星际轨道捕获时的系绳控制问题,首先对运行在目标行星双曲线飞越轨道上的探测器系统进行动力学建模,给出了一致性轨道捕获条件和系绳最佳切断点,并进行了动力学特性分析。考虑到子探测器捕获后的变轨需求及系绳收放速率的限制,提出了新的最优控制方法,并应用模拟退火算法进行了数值求解。仿真结果表明,系绳切断时指向恰当,子探测器距离目标行星最近,将有利于后续变轨；系绳最大收放速率约为30 m/s,切实可行。

Tether control of the momentum-exchange tether assisted interplanetary orbital capture in deep space exploration was studied.Firstly,the dynamic model of a detector system in a hyperbolic flying orbit was established.Secondly ,the consistent condition of orbital capture and the optimum tether cut-off point were derived to analyze the dynamic characteristics. Finally, considering the sub-detector's post-capture orbit maneuver requirements and limitation of the tether deployment/retrieval velocity, a new optimal control problem was proposed and numerically solved by the simulated annealing algorithm. Simulation results show that the tether orientation is appropriate at the cut-off point and will be beneficial for the following orbit maneuver,and the maximum tether deployment/retrieval velocity is about 30 m/s.
