将模糊数学方法引入到民机机载气象雷达故障诊断中,提出由历史数据及专家择优综合确定模糊隶属度的方法,建立了模糊故障诊断模型,准确、快速地找出故障原因,实践证明该模型合理有效。 The fuzzy mathematics method is introduced into the fault diagnosis of civil aircraft airborne radar, and the method of determining the fuzzy membership degree based on historical data and expert selection is proposed. The fuzzy fault diagnosis model is established to find the cause of the fault accurately and quickly. The model is reasonable and effective.
