摘　　要：针对可重复使用运载器(RLV)末端能量管理过程中制导与控制系统的性能好坏,提出了一种基于评价指标体系的定量评估方法.讨论了飞行器末端能量管理过程中主要影响指标,介绍了指标值的获取方法、归一化处理方法以及利用AHP层次分析法和熵值法相结合的主客观结合赋权法获得指标权重的过程并以此为基础构建了自上而下分别为目标层、准则层、指标层的末端能量管理段评估指标体系结构,最后通过仿真完成定量评估过程.所提出的方法可成功应用于可重复使用运载器末端能量管理段制导与控制系统的性能评估,显著缩小飞行器验证时间和成本.Aiming at evaluating the performance of guidance and control system in the process of RLV＇s Terminal Area Energy Management,This paper proposes a quantitative evaluation method based on the evaluation index system. It discusses the main impact index of vehicle in the process of TAEM,introduces the method of index access,the normalized processing method and the method of index weight access by using Analytic Hierarchy Process combined with the Entropy Value Method.On this basis builds the top-down TAEM＇s evaluation index system structure. In the end,completing quantitative assessment process through simulation. The proposed method can be successfully used in the process of performance evaluation of the guidance and control system in the process of RLV＇s TAEM,it can significantly reduce vehicle verification time and cost.
