基于多源信息融合的模糊理论在引气系统故障诊断中的应用

介绍了多源信息融合理论、模糊理论以及民用飞机引气系统的原理,建立了基于多源信息融合的模糊故障诊断模型,对引气系统进行了实例诊断。实例诊断结果表明:模糊理论及其多源信息融合理论在民用飞机引气系统故障诊断中的应用解决了长期以来困扰引气系统故障诊断中时间长、部位不清、原因不明的问题;使引气系统故障诊断科学化、规范化,提高了诊断的准确性、快速性。

Application of Fuzzy Theory Based on Technology of Multi-source Information Fusion on Bleed System Fault Diagnosis Methods

This paper first introduces the principle of the bleeding system and technology of multi-source information fusion and fuzzy theory, and then established the fault diagnosis model based on the technology of multi-source information fusion and fuzzy theory, and finally make a diagnosis example for the Bleeding system of civil aircraft. The application of fuzzy theory and technology of multi-source information in the fault diagnosis of Bleeding System of civil aircraft resolves the problem during bleed system fault diagnosis which were long time, not clear, unknown reasons so as to made bleed system fault diagnosis scientific, standardized, accuracy and rapidity.
