摘要
本文介绍空间飞船再入段最优制导方法。纵向制导采用二次型性能指标最优的线性系统,得到最优控制规律。侧向制导利用庞特里亚金最小原理,得到最优开关曲线。结果表明,这些控制规律优于Rodney C.所介绍的制导方法。
This paper presents the optimal guidance method for the re—entry stage of a manned space-ship.The longitudianl guidance uses an optimal linear system with quadratic criteria,from whichthe law of optimal guidance can be obtained.The lateral guidance uses the Pontryagin minimumprinciple,from which the switch curve of lateral control can be obtained.The control laws ob-tained here are better than those described in reference.
