Engineering Approach for Airborne Diagnostic Model Establishment

摘要:

建立准确、有效的机载诊断模型是飞机健康管理系统能力提升中最为核心的技术问题。在分析国内外故障诊断模型开发方法研究现状的基础上，对机载诊断模型的工程化开发方法进行了深入研究。重点阐述了基于模型的故障诊断原理、机载诊断模型建立流程，并设计和实现了相应的机载诊断模型工程化开发辅助工具，其阶段性成果已在实际的工程项目中得到应用和验证。

Abstract:

The establishment of accurate and effective onboard diagnostic models is the core technical problem for the capability improvement of aircraft health management system. Based on the analysis of the research status at home and abroad, an engineering development approach for onboard diagnostic models is presented. The principles of model-based diagnosis and the establishment process of onboard diagnostic models are expounded. Besides, an auxiliary tool is developed to standardize the models. The achievements have been applied in actual project and proved to be effective.
