Development and application of prognostics and health management technology

Prognostics and health management (PHM) refers to functions that equipment in use can automatically complete the fault detection, prediction, isolation and monitoring, and timely fault impact assessment, fault report and condition monitoring management. This paper analyzes the requirement of engineering application and development of PHM technology. It focuses on three aspects technical problems of the application of PHM technology, including fault diagnosis and prediction model based on physics-of-failure (PoF), data mining technology and special sensors for critical failure mechanism of MOS devices. Correspondingly, present research work on these three aspects is introduced.
