A Survey of the Guidance Methods for Spacecraft

介绍了临界极值的概念 ,在分析反馈策略的基础上 ,给出了一种次优反馈控制律。提出并讨论了 3种数学方法 :次优反馈策略、重复纠正法和连续重复纠正法。

This paper introduces the concept of neighboring extremals. A neighboring optimal control law is given after the analysis of feedback strategy. Then three numerical methods are discussed: neighboring optimal feedback strategy, iterative correction method and continuous iterative correction method. The first two methods have been validated in the guidance of spacecrafts.
