涡轴发动机控制系统综合评价方法

为综合评价涡轴发动机的全权限数字式电子控制系统,在参考GJB 4078的基础上,结合涡轴发动机及控制系统自身特点,基于模糊层次分析法提出了适用的评价指标体系。通过专家打分确定评价指标体系中定性指标和定量指标的权重,建立评语集合,利用模糊层次分析法,解决了定性和定量指标混合评价时模糊量明显化的问题,有利于更加科学地综合出评价结果。同时,分别用某一定性指标和定量指标作为算例,验证了模糊层次分析法的合理性和可行性。

Comprehensive Evaluation Method of Turboshaft Engine Control System

To evaluate full authority digital electronic control system of a certain type of turboshaft engine, combined with the characteristics of turboshaft engine and control system, suitable evaluation index system was put forward based on fuzzy analytic hierarchy process and GJB 4078. Weight of qualitative index and quantitative index were determined by expert scoring, establish evaluation collection. By using fuzzy analytic hierarchy process, the problem of obvious fuzzy quantity in mixed evaluation of qualitative and quantitative indexes was solved. It is conducive to making a more scientific result. At the same time, use qualitative indexes and quantitative indexes as computational examples, the rationality and feasibility of fuzzy analytic hierarchy process were verified.
