本文讨论了系统的故障诊断问题,概述了几种常用的基于解析余度技术的故障诊断方法,并对这些方法的原理、特点作了简要介绍。文末指出了设计对模型误差鲁棒的故障检测方法将是以后的主要研究方向。
This paper discusses the problems of system fault diagnosis, summarizes several commonly used fault diagnosis methods based on analytic redundancy technology, and gives a brief introduction of the principle and characteristics of these methods. At the end of this paper, it is pointed out that the design of the fault detection method robust to model errors will be the main research direction later.
