摘　　要：本文首先概述了控制系统故障诊断的概念,分析了国内外对于这一领域的研究水平和发展状况,并且分基于和不依赖于控制系统数学模型两大类介绍了一些主要的故障诊断方法。此外,本文针对当前应用较多的一种动态系统——混合系统,提出了一种基于键合图模型的故障诊断方法。介绍了混合键合图基本原理,通过混合键合图对混合动态系统建模,为进一步进行MBD故障检测和追踪直至故障隔离和鉴别提供基础模型。This paper presents firstly the basic principles of the fault diagnosis about control system, and then analyzes the situation of research and the development in this topic. Finally, the fault diagnosis techniques which are based on the model or independent of the model are discussed in detail. In addition, in view of the more applications of a dynamic system - hybrid system, a bond graph model-based fault diagnosis method is proposed, and its basic principle is also explained in this paper. Modeling by hybrid bond graph provides a basic method to further carry on the MBD failure detection and tracking.
