A self-validating control system based approach to plant fault detection and diagnosis
Jun Chen,John Howell +1 more
TLDR
In this paper, 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.About:

Progress in root cause and fault propagation analysis of large-scale industrial processes
Fan Yang,Deyun Xiao +1 more
TL;DR: In large-scale industrial processes, a fault can easily propagate between process units due to the interconnections of material and information flows so the problem of fault detection and isolation for these processes is more concerned about the root cause and fault propagation before applying quantitative methods in local models.

Real-Time Monitoring of Complex Industrial Processes with Particle Filters
TL;DR: It is shown that the overhead of the extra processing per particle of the more sophisticated methods is more than compensated by the decrease in error and variance.

A survey of the state of condition-based maintenance (CBM) in the nuclear power industry
R.M. Ayo-Imoru,A.C. Cilliers +1 more
TL;DR: In this paper, the authors present a survey on the state of condition-based maintenance in the nuclear industry, which is achieved by systematically looking at the major phases of CBM, which are monitoring, diagnostics and prognostics.

A qualitative physics based on confluences
Johan de Kleer,John Seely Brown +1 more
TL;DR: A fairly encompassing account of qualitative physics, which introduces causality as an ontological commitment for explaining how devices behave, and presents algorithms for determining the behavior of a composite device from the generic behavior of its components.

Statistical Process Control of Multivariate Processes
TL;DR: An overview of multivariate statistical methods use for the statistical process control of both continuous and batch multivariate processes and examples are provided of their use for analysing the operations of a mineral processing plant, for on-line monitoring and fault diagnosis of a continuous polymerization process and for the on- line monitoring of an industrial batch polymerization reactor.

Assessment of control loop performance
TL;DR: In this article, an estimate of the best possible control can be obtained by fitting a univariate time series to process data collected under routine control, and the use of this technique is demonstrated with pilot plant and production data.
