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。
In order to comprehensively evaluate the full authority digital electronic control system of turboshaft engine, based on the reference of GJB 4078 and combining with the characteristics of turboshaft engine and control system, a suitable evaluation index system is put forward based on fuzzy AHP. Through expert scoring, the weight of qualitative index and quantitative index in the evaluation index system is determined, and the comment collection is established. The fuzzy analytic hierarchy process is used to solve the problem of the obvious fuzzy quantity in the mixed evaluation of qualitative and quantitative indexes, which is helpful to synthesize the evaluation more scientifically result. At the same time, using a certain qualitative index and quantitative index respectively as an example, the rationality and feasibility of fuzzy analytic hierarchy process are verified.
