摘　　要：载人登月转移轨道是指地月转移轨道和月地返回轨道,其上飞行器飞行时间长、动力学模型复杂、非线性强且变系数.因此,工程任务中偏差不可避免,对偏差的控制直接影响任务执行的效果甚至成败.在概述载人登月转移轨道研究基础上,总结了偏差传播分析方法、最优中途修正策略及中途修正瞄准算法.最后,对我国未来载人登月转移轨道中途修正提出一些建议.The transfer orbit for the human lunar mission means that between the trans-lunar orbit and the trans-earth orbit, and it has the characteristics of long flight time, complex dynamics model, and strong nonlinear and variable coefficients. The controllability of the inevitable deviation affects the result of the task execution, even the success or the failure of the engineering task directly. This paper reviews the studies of the transfer orbit of human lunar mission, the analysis method of the deviation propagation, the mid-course correction optimal strategy and the mid-course correction aiming algorithm. At last, some suggestions are madefor the mid-course correction of the Chinese human lunar mission in the future.
