制导控制系统的多准则变权综合评估方法

Multi Criterion Variable Weight Comprehensive Evaluation Method of Guidance and Control System

制导控制系统性能评估工作在飞行器研发过程中必不可少,然而完整的综合评估方法和相应的支撑工具目前还比较缺乏。鉴于此,对飞行器制导控制系统性能评估方法进行研究,分析了系统的结构关系,建立了层次化的性能评估指标体系;针对飞行器评估的数据可靠性、指标分辨度不一等特点,提出了多准则构权的变权综合方法;最后给出了飞行器制导控制系统性能评估实例。实例表明,所提出方法的定权依据较为科学,并且可以兼顾系统的均衡性给出合理评价结果,为制导控制系统性能评估提供了可用方法和工具。

The evaluation of guidance and control system is necessary in the process of vehicle development. In view of lacking of effective comprehensive evaluation methods and the corresponding auxiliary software, the performance evaluation methods of vehicle guidance and control systems are researched, the structure of the system is analyzed, and a hierarchical performance evaluation index system is established. Considering the varying degrees of the data reliability and independence of each index, a variable-weight comprehensive method with multi-criteria is proposed. A performance evaluation example of vehicle guidance and control system is given which shows that the proposed method weights the index comprehensively. A reasonable evaluation result is given considering the balance of system performance, which provides available method for the follow-up guidance and control system performance evaluation.
