摘要:
由于小行星具有引力场不规则、物理参数不确定性大、表面逃逸速度小等因素,使得小行星附近制导和控制极具挑战性。回顾了小行星探测任务的历史、现状和意义;针对小行星附近制导与控制研究的基础即小行星附近动力学,分析了研究现状;针对悬停、绕飞、转移、着陆等任务形式,详细介绍了轨道制导和控制方法方面的热点问题和研究现状;基于研究现状,列举了部分未来可进一步研究的方向和问题。

Abstract:
Asteroid exploration has become an important part of interplanetary missions because of its important scientific significances and engineering values. However, difficulties such as irregular gravity, unknown physical parameters and low escape velocity of asteroids make guidance and control in the vicinity of asteroids very challenging. In this paper, the history, current status and significances of asteroid missions are introduced. Then,the dynamics in the vicinity of asteroids, which are the foundation for studying the guidance and control in the vicinity of asteroids,are introduced. Thereafter,the hot issues and research status of methods of guidance and control for different missions which include hovering, parking orbits, orbit transfer, and landing are discussed in detail. In the conclusion,some relevant directions and problems for future researches are listed based on the research status.
Key words:  asteroid exploration;dynamics;guidance;orbit design;control
