模糊推理在军用飞机转速摆动故障诊断中的应用研究

Simulation Research of Build of Fuzzy Fault Diagnosis Model of Military Plane′s Revolution Swing

鉴于目前军用飞机维护人员故障处理效率低以及传统故障诊断技术不能充分吸收人类经验的情况,文中运用模糊推理技术,模拟专家故障诊断推理过程,建立了某型军用飞机发动机转速摆动故障的模糊故障诊断模型,并构建了故障诊断系统,对其进行仿真研究;仿真结果表明所建立的模型可以很好地吸收维护人员的故障诊断经验,对故障原因可做出准确判断。

Considering the inefficiency of contemporary methods used by the maintainers of military plane and the fact that traditional fault diagnosis can＇t ahsorb human＇s experiences well, this paper simulated the procedure of expert＇s interference with fuzzy interference to build a fault diagnosis model, and a fault diagnosis system was huilt. The result of simulation proved that this model can absorb the experiences of human and make accurate judgment.
