摘　　要：小天体探测是未来深空探测的重点领域之一,而小天体附近轨道动力学与控制问题是小天体探测任务迫切需要解决的关键问题.该问题涉及形状不规则小天体附近的动力学环境建模与小天体附近轨道动力学机理.本文从不规则形状小天体引力场的建模、小天体附近的自然轨道动力学、小天体附近的受控轨道动力学3个方面综述了小天体附近轨道动力学与控制的研究现状与发展趋势,并分析了小天体附近轨道动力学所面临的挑战与难题,最后对我国未来小天体探测任务可能涉及的轨道动力学与控制问题的发展方向进行了展望.Small celestial body exploration is one of tile key areas of deep space exploration in the fllture. The orbital dynamics and control problem near small celestial bodies is crucial in such explorations, and urgent to be treated. This problem involves the modeling of dynamics environment around an irregular- shaped small celestial body, and the orbital dynamics mechanism near tile small celestial body. In this paper, we survey the gravitational field modeling of irregular-shaped small celestial body, natural orbital dynamics and control, and controlled orbital dynamics near small celestial body. We introduce state-of- the-art and trends for the development of orbital dynamics and control near small celestial bodies. The challenges and difficulties encountered are analyzed. Finally, we discuss the prospects for the development direction and key issues of orbital dynamics and control for Chinese future mission for exploring small celestial bodies.
