Rule-based reduction of alarm signals in industrial control
TL;DR: This paper presents a methodology and a computerized tool that aims to remove nuisance alarms, a so-called alarm cleanup, that takes advantage of the control system's built-in functions, and is a first step to an improved overall alarm situation.

Optimal statistical fault detection with nuisance parameters
M. Flouladirad,Igor Nikiforov +1 more
TL;DR: Fault detection is addressed within a statistical framework with particular emphasis on dealing with nuisance parameters and the corresponding inference problem is stated.

A New Approach to Multiple Fault Diagnosis: A Combination of Diagnostic Matrices, Graphs, Algebraic and Rule-Based Models. The Case of Two-Layer Models
TL;DR: Several possible interpretations of the diagnostic matrix with rule-based systems are provided and analyzed and an approach to the diagnosis of multiple faults based on inconsistency analysis is outlined, and a refinement procedure using a qualitative model of dependencies among system variables is sketched out.

Fault tolerant control of an autonomous underwater vehicle under thruster redundancy: simulations and experiments
TL;DR: In this article, a redundancy resolution scheme is presented that takes into account the presence of excess number of thrusters along with any thruster faults and determines the reference thruster forces to produce the desired motion.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.

Analytical redundancy and the design of robust failure detection systems
E. Chow,Alan S. Willsky +1 more
TL;DR: In this article, a robust failure detection and identification (FDI) process is viewed as consisting of two stages: residual generation and decision making, and it is argued that a robust FDI system can be achieved by designing a robust residual generation process.
A survey of design methods for failure detection in dynamic systems
TL;DR: A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.
