地月转移器作为载人登月飞行器的重要舱段,执行奔月加速、中途轨道修正和近月制动减速任务。针对地月转移器的任务要求,分析飞行任务对制导、导航和控制(GNC)系统的需求,总结GNC系统的特点,分解GNC系统的任务与功能,提出地月转移器GNC系统的组成和初步方案设想,提出系统中的关键技术,重点对地月转移器弹性振动及液体晃动的抑制策略进行探讨,对交会逼近段和地月转移加速段的控制进行仿真,为地月转移器的GNC方案论证提供部分参考依据。
As the important section of the manned lunar spacecraft, the earth-moon transfer device performs the tasks of flying towards the moon, accelerating mid-course, and braking in recent months. According to the mission requirements of earth-moon transferor, the requirements of flight mission guidance, navigation and control (GNC) system are analyzed, the characteristics of GNC system are summarized, the tasks and functions of GNC system are decomposed, and the composition and preliminary of GNC system In this paper, the key technologies in the system are put forward, and the control strategy of the elastic vibration of the earth-moon transfer device and the liquid sloshing is discussed. The control of the approach approximation and the acceleration of earth-moon transfer are simulated. Argumentation provide some reference.
