Fault diagnosis for a turbine engine
Yixin Diao,Kevin M. Passino +1 more
TL;DR: A sophisticated component level model (CLM) simulation of a turbine engine (XTE46) that can simulate the effects of manufacturing and deterioration differences, in addition to a variety of failures, is dealt with.
Journal ArticleDOI
Relaxed maximum a posteriori fault identification
TL;DR: This work considers the problem of estimating a pattern of faults, represented as a binary vector, from a set of measurements, and shows that the method performs extremely well, both in identifying the true fault pattern, and in identifying an ambiguity group.

A tractable nonlinear fault detection and isolation technique with application to the cyber-physical security of power systems
TL;DR: A novel methodology to robustify a linear residual generator for a nonlinear system in the presence of certain disturbance signatures is proposed and used to diagnose a cyber-physical attack emanating from the vulnerabilities introduced by the interaction between IT infrastructure and power system.
Proceedings ArticleDOI
A robust fault detection and isolation scheme for a class of uncertain input-output discrete-time nonlinear systems
TL;DR: This paper extends very recent results on discrete- time nonlinear fault detection and isolation to the case of discrete-time nonlinear systems with unstructured modeling uncertainty and partial state measurement and design adaptive residual thresholds associated with each isolation estimator and obtain sufficient conditions for fault isolability.

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.
