自动控制系统故障诊断技术的发展与展望

The Development and Prospect of Fault Diagnosis in Automatic Control Systems

通过将自动控制系统的故障诊断分为基于数学模型的方法、基于信号处理的方法和基于知识的方法三大类进行讨论,得出了故障诊断技术的发展概况与发展趋势。进一步给出了故障诊断技术典型新应用,并指出了故障诊断技术中存在的问题和未来的研究重点。

This paper aims to reveal the status quo and the trend of the development in the field of the fault diagnosis of automatic control systems by the discussion on the three categories of the fault diagnosis methods:methods based on mathematic model,methods based on signal processing,and methods based on knowledge.Besides,some typical new applications of fault diagnosis are introduced in this paper.Then,the potential problems in this area are outlined and the future important research directions are pointed out.
