摘要
设备运行状态的识别，是设备故障诊断的核心。由于对设备状态引起的各种特征值的评价具有一定的模糊性．因此模糊模式识别就成为设备状态识别的一种有力方法。本文从特征提取、隶属函数建立、识别判决等几方面对模糊识别在设备运行状态识别中的应用进行了探讨和分析。
The recognition of equipment operating state is the heart of equipment fault diag- nosis. Since the evaluation of equipment state feature values has some fuzzy factors, fuzzy mode recognition becomes one powerfull method of equipment state recognition.In this paper the appli- cation of fuzzy recognition to equipment operating state recognition is discussed and analyzed in f eature extraction, membership function, and identification analysis.
