Qu Li, Zhang Hai-ju · Zhongguo jixie gongcheng · 2001
Fault diagnosis includes data collection, signal analysis, feature extraction and decision making. Each of them is important to make the diagnostic decision. This paper discusses how to improve diagnostic quality and reliability through appropriate signal analysis methods. Some effective ways are proposed to improve diagnostic quality,such as noise suppression, information integration and fusion, information decomposition and feature trending. Examples reveal their effectiveness.
