DISCUSSION OF SOME IMPORTANT ISSUES OF OBSERVER BASED FAULT DIAGNOSIS TECHNIQUE

基于观测器方法的故障诊断技术近年来得到了迅速发展，取得了许多可喜的成果．该文探讨了这一领域中一些重要的热门研究问题，包括：基于观测器方法的检测与诊断系统的分析与评价方法，以及基于观测器的检测系统的设计方法．重点介绍作者在这一领域的一些最新研究成果，如故障空间的划分，检测系统的集成设计方法等．

In recent years observer based fault diagnosis technique is developed rapidly, and has led to many new results. In this paper, some important issues in this area, including analysis and evaluation of observer based detection and diagnosis system, and design method of this technique, are discussed. The emphasis is focused on some latest approaches proposed by the authors, such as the division of the fault space, the integrated design method of the detection system, etc.
