Complicated Manufacturing System Dynamic Measure-Control and Intelligence Diagnosis

Abstract

As an important mean to ensure machining accuracy, the dynamic measurement and intelligent fault diagnosis technology can be used in aviation manufacturing machine. In recent years, several theoretical results are gotten on weak signal feature extraction, multiple sensor information fusion of early fault identification as well as the set up of embedded online monitoring units. This article is the summary of those results, the existing problems is analyzed, and the trend of the development in this field is also discussed.
