A self-validating control system based approach to plant fault detection and diagnosis [PDF]

open access: yes, 2001
An approach is proposed in which fault detection and diagnosis (FDD) tasks are distributed to separate FDD modules associated with each control system located throughout a plant.

Fault Relevant Variable Selection for Fault Diagnosis [PDF]

open access: yesIEEE Access, 2020
In process monitoring, fault relevant variable selection and fault diagnosis are two important branches. But they are often discussed independently and scarcely integrated in research. To integrate them, a novel fault diagnosis algorithm based on fault relevant variable selection is proposed in this paper.
