基于人工智能的故障诊断方法的新发展

纵缆了在采用人工智能方法的动态系统中模型的故障诊断技术，以一个典的自动控制系统为例，说明了故障的类型及故障诊断的基本任务。阐述了基于知识模型的残差产生办法。

NEW DEVELOPMENTS USING AI IN FAULT DIAGNOSIS

A survey on the state of the art of model based fault diagnosis for dynamic processes is given.A typical automatic control system is given to illustrate types of faults and the basic tasks of fault diagnosis.Knowledge based methods of residual generation are presented.Emphasis is placed upon the use of fuzzy models for residual generaton.The application of qualitative model based fault diagnosis in electrical circuits fault diagnosis is introduced.The art of fault diagnosis which is verified by practice is practical and superior to the traditional fault diagnosis art,because the knowledge acquisition can be simplified.ln the end,the basic idea of a novel observer concept,the so called "knowledge observer", is provided.
