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:

Consistent malfunction diagnosis inside control loops using signed directed graphs
TL;DR: In this article, a unified signed directed graph (SDG) model for control loops is proposed, in which both disturbances (sensor bias etc.) as well as structural faults can be easily modeled.
Journal ArticleDOI
Root cause analysis of oscillating control loops
TL;DR: In this article, an approach that uses detailed oscillation characterization in combination with signed digraphs is proposed for isolating the source loop that causes plant-wide oscillation in a single control loop can propagate to many units and can cause several control loops to oscillate.

Neri project 99-119. task 1. advanced control tools and methods. final report
TL;DR: In this article, the authors present a new paradigm for automated development of highly reliable control architectures for future nuclear plants, which can be traced directly to the design requirements, such as high-level requirements and stress factors.

Qualitative process theory
TL;DR: This paper describes the basic concepts of qualitative process theory, several different kinds of reasoning that can be performed with them, and discusses its implications for causal reasoning.

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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
