摘要

本文重点研究了应用基于数学模型的汽车柴油机气路结构分析方法来实现故障检测与隔离的目的。为了简化结构分析过程，将气路系统模型转化为结构状态方程。为了研究系统的单性性，本文讨论了如何生成非线性解析冗余关系。结果表明，该方法可以检测到所有指定的故障，但有些故障不能隔离。

Structural analysis for air path of an automotive diesel engine

The paper focuses on the application of structural analysis based on mathematical model of air path of an automotive Diesel engine to realize the objective of fault detection and isolation. The model of the air path system was transformed into structural state equations in order to simplify the procedure of structural analysis. The paper is concerned on how to generate nonlinear analytical redundancy relations in view to study the monotorability of the system. The results show that all specified faults can be detected but some of therm can not be isolated.
