提出了一种基于Mamdani模糊推理的航空发动机故障诊断方法。该方法将发动机故障征兆信号作为模糊推理的输入，利用专家经验建立模糊推理规则并提取蕴含关系，在此基础上，通过故障征兆信号与蕴含关系的 Mam-dani推理合成获取发动机故障原因发生的可能性，进而达到故障诊断的目的。实验结果表明，该方法可行且有效。

A diagnosis method of aeroengine faults based on Mamdani fuzzy inference is proposed in this paper.Using aeroengine fault symptoms as inputs,the proposed method establishes rules of inference by employing experts’experience and distills the implication relationships.By means of Mamdani inferential composition of the fault symptoms and the implication relationships,the prob-ability of the occurrence of engine fault causes is obtained and the purpose of diagnosing faults is therefore achieved.Experimental results show that this method is both feasible and effective.
