Abstract

Highlights A multi-factor aging physical model incorporating knee point information is proposed. Achieving end-to-end accurate prediction of knee points and RUL based on CNN. Integration of physical and data-driven models for accurate degradation prediction. Deep coupling of remaining useful life prediction with degradation trajectory prediction. Limited training data shows strong early prediction capability.
