摘要
结合目前已实施的小天体附着探测任务,对小天体探测器主动附着涉及的制导与控制技术进行了系统性的回顾。首先,针对小天体附着任务风险高、不确定性强的特点,明确了主动附着的内涵,并分析了现有附着探测技术在自主性和安全性上面临的挑战,阐述了提高探测器主动附着能力的重要性。在此基础上,归纳梳理了与主动附着相关的制导与控制技术最新研究进展。最后,结合未来小天体探测任务需求,总结了今后具有进一步研究价值的几个问题。
Combined with missions of landing on small celestial bodies that have been implemented so far,a systematic review of guidance and control technologies involved in the small celestial body active landing is carried out.First of all,according to the characteristics of high risk and high uncertainty of small celestial body landing missions,the connotation of active landing is clarified,and the challenges in autonomy and safety of existing landing technologies are analyzed.The importance of improving the active landing ability of small celestial body explorers is expounded.On this basis,the latest research progress of guidance and control technologies related to active descent and landing are summarized.In the end,combined with the requirements of future small celestial body exploration missions,several issues with further research value are listed.
