摘　　要：连续小推力非开普勒悬浮轨道在深空探测与地球极地观测任务中有着重要的应用前景。归纳了电推进、太阳帆推进等连续小推力技术的发展历程与现状;阐述了日心、行星悬浮轨道的动力学特性、稳定性、轨道保持策略;分析了三体问题下人工拉格朗日点的优势及其在深空探测方面的应用;讨论了悬浮轨道编队飞行的研究方法与控制策略。最后针对小推力悬浮轨道研究发展面临的难题,提出了研究新思路和应用新方向。The non-Keplerian displaced orbits by low-thrust propulsion have significant applications in observation missions of the deep space and Earth polar region.The development of the continuous low-thrust propulsion technology represented by the electric propulsion and solar sail propulsion was detailed.The heliocentric and planetary displaced orbits were discussed to reveal the nonlinear dynamical characteristics,stability and orbit keeping strategies.The advantages of artificial Lagrangian points generated in the three-body problem were analyzed as well as its application in deep space explorations.Moreover,the relative dynamics and control of formation flying in displaced orbits were discussed.Finally,new research directions and applications were proposed for the research challenges of displaced orbits by low-thrust propulsion.
