Kronecker Maps and Sylvester-Polynomial Matrix Equations
Ai-Guo Wu,Guang-Ren Duan,Yu Xue +2 more
TL;DR: With the help of the Kronecker maps, general explicit solutions of the Sylvester-polynomial matrix equations are established when the polynomial matrices possess F-primeness.
Journal ArticleDOI
Robust feedback design with optimized diagnostic performance
TL;DR: This paper is concerned with the design of reconfigurable control laws that also effectively facilitate the acquisition of information used for diagnostic purposes in fault tolerant control systems.

Modeling electromagnetic disturbances in closed-loop computer controlled flight systems
W.S. Gray,Oscar R. Gonzalez +1 more
TL;DR: In this paper, an electromagnetic disturbance model is introduced for stability analysis and augmentation of any digitally implemented control law, composed of a Markovian exosystem supplying radiation events to a discrete-time jump linear system which models how the radiation interferes with the nominal operation of the closed-loop system.
Journal ArticleDOI
Diagnosability of intermittent sensor faults in discrete event systems
TL;DR: The model of intermittent loss of observations proposed in the literature is modified to account for sensor malfunction only and a test based on diagnoser automaton is proposed to verify intermittent sensor fault diagnosability.

On-line multivariate analysis in a distributed process control system
TL;DR: In this article, a method and system for monitoring a process in a process plant includes collecting data from a process control system within the process plant, where the data is representative of a normal operation of the process when the process is on-line and operating normally.

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.
