平动点轨道的动力学与控制研究综述

Overview of Orbital Dynamics and Control for Libration Point Orbits

平动点轨道在深空探测领域具有重要的应用价值,引起了国内外航天界的密切关注。详细介绍了平动点轨道的发展历史,并深入剖析平动点附近的相空间结构和同\异宿连接的力学机制;论述Halo轨道转移方式的实现、轨道维持策略及平动点轨道的姿态描述,然后讨论了实现深空组网的平动点星座建立。平动点具有十分丰富的内容,在轨道动力学其他领域亦有扩展,细致分析了平动点理论在地月转移、太阳帆轨平动点以及近地编队飞行等方面的应用。

Libration point orbits have the important applications in deep space exploration, and have been paid more attentions from all over the world. This paper goes into detail about the history of the development for the libration point orbits, and analyzes the structure of phase space and the phenomenon of homoclinie／heterclinic connections. It is addressed that the different transfers from Halo orbit to Earth, including the strategy of stationkeeping maneuver and the descriptions of attitudes, and then the constellation for deep exploration is treated. Libration point has the wide extensions into other fields of orbital dynamics, such as the cislunar transfer, sail equilibrium and formation flying in the gravitation if Earth which are highlighted in this paper.
