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若干重要问题的探讨

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.
