摘要
对故障诊断问题进行了数学描述,强调了模式识别和故障诊断之间的联系,研究了基于模式识别的故障诊断过程及一般自适应诊断系统的设计理论,并重点讨论和分析了数据参数化、模式类构成、特征选取和分类器设计的具体实现过程。最后,提出了设计自适应诊断系统时的难点和应该考虑的一些问题。
First, link between pattern recognition and fault diagnosis and mathematical formulation of the pattern classification problem are presented in this paper. Second, the diagnosis procedure based on pattern recognition and design of a common adaptive diagnosis system are studied with emphasis on data parameterization, formation of the pattern classes, feature selection and classifier design. Finally, some difficulties and problems that should be considered are given out when an adaptive diagnosis system is designed.
