Optimally robust redundancy relations for failure detection in uncertain systems
TL;DR: The problem of determining redundancy relations that are optimally robust is addressed in a sense that includes several major issues of importance in practical failure detection and that provides a significant amount of intuition concerning the geometry of robust failure detection.

A new structural framework for parity equation-based failure detection and isolation
Janos Gertler,David A. Singer +1 more
TL;DR: A new framework for developing parity equations that prevent incorrect isolation decisions under marginal size failures in a decision process that tests each residual independently is described.
Journal ArticleDOI
Robust Model-Based Fault Diagnosis: The State of the ART
TL;DR: In this paper, the authors review methods for robust fault diagnosis, based principally on residual generation, and some of the key challenges and potential for future directions in the research are drawn up.

Observer-Based Fault Detection for Nonlinear Systems With Sensor Fault and Limited Communication Capacity
TL;DR: A new fault detection design scheme is proposed for interval type-2 (IT2) Takagi-Sugeno (T-S) fuzzy systems with sensor fault based on a novel fuzzy observer to verify the effectiveness of the presented scheme.

Fault diagnosis with multivariate statistical models part I: using steady state fault signatures
Seongkyu Yoon,John F. MacGregor +1 more
TL;DR: In this paper, the authors present a fault detection approach based on the vectors of movement of a fault in both the model space and the residual space, which are then compared to the corresponding vector directions of known faults in the fault library.

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.

Parameter estimation for continuous-time models-A survey
TL;DR: The paper reviews the progress of research on parameter estimation for continuous-time models of dynamic systems over the period 1958-1980 and includes a classification system which conforms as closely as possible to that which has arisen naturally over the past two decades.
