微小故障诊断方法综述

针对微小故障的特点,提出将微小故障分为缓变微小故障、突变微小故障和间歇性微小故障,并进一步提出微小故障诊断方法的分类框架,将微小故障诊断方法分成了3类,即定性诊断方法、定量诊断方法和半定性半定量诊断方法.对每一类中现有的微小故障诊断方法再次归类,并对每种方法的基本思想、研究进展、适用条件和应用等进行了介绍.最后探讨了微小故障诊断有待解决的问题.

Review of incipient fault diagnosis methods

According to their characteristics, incipient faults are divided into gradual incipient faults, abrupt incipient faults and intermittent incipient faults. Furthermore, we propose a classification framework of diagnosis methods for incipient faults, and classify all incipient falut diagnosis methods into three categories, i.e., qualitative diagnosis methods, quantitative diagnosis methods, as well as semi-qualitative semi-quantitative diagnosis methods. Each category of existing incipient falut diagnosis methods is further subdivided. The basic ideas, research progresses, application conditions and applications of every method are discussed in details. Finally, some open problems in this area are introduced.
