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.
Manned lunar transfer orbit refers to the earth-moon transfer orbit and lunar return orbit, the flight time of the aircraft is long, the dynamic model is complex, and the nonlinearity is strong and the coefficient is variable. Therefore, the deviation of the project task is inevitable and the deviation control Which directly affects the success or failure of the task execution.On the basis of an overview of manned lunar transfer orbit research, the methods of deviation propagation analysis, the optimal midway correction strategy and the mid-course correction targeting algorithm are summarized.Finally, the future manned lunar transfer orbit Midway amendments made some suggestions.
