FUZZY数学在汽车电喷发动机故障诊断中的应用

Application of Fuzzy Mathematics to Diagnosis of Auto Malfunction of Electrical Jet Engine

将模糊数学方法引入到汽车电喷发动机故障诊断中,提出了由历史数据及专家优序数综合确定模糊隶属度的方法,建立了模糊诊断模型,解决了针对一种或数种故障征兆,如何准确、快速地找到引起故障的真正原因,从而为汽车的故障诊断维修工作提供了一种科学、可行的新方法.

In this thesis, we apply fuzzy mathematic method to the diagnosis of auto malfunction of electrical jet engine and bring forward setting up the fuzzy membership grade method which is based on the history data and expert preferential ordinal number. The fuzzy diagnostic model is founded to resolve one or several malfunctions and find the causes of macfunctions accurately. Finally, a scientific and feasible new method is offered to the auto malfuntion diagnosis service.
