Fault detection and isolation in nonlinear systems

1999 European Control Conference (ECC), 1999
In this paper the problem of fault isolation in non linear systems is considered. Faults are formulated as parameter changes and a novel definition of fault detent ability is introduced. This connects a fault with its effect on the output of the system under consideration.

Fault Detection and Isolation for State Affine Systems

European Journal of Control, 1998
The problem of residual generation for fault detection and isolation (FDI) in state affine systems is studied. The fundamental problems of residual generation is stated for state affine systems up to output injection. Sufficient conditions for the existence of a solution is presented by making use of Kalman-like observers.

A geometric approach to nonlinear fault detection and isolation

IEEE Transactions on Automatic Control, 2000
The dual concepts of unobservability distributions and observability codistributions proved to be very useful to deal with problems of fault detection in linear control systems with disturbances. This paper extends an approach used for linear systems to the class of control-affine (nonlinear with respect to state) systems.

Energetic approach to parametric fault detection and isolation

Proceedings of the 2004 American Control Conference, 2004
This paper concerned with the diagnosis and identification of parametric fault which may occur in a physical system. The method uses a bond graph system model to generate residual signals for fault diagnosis. Fault identification of system parameters is obtained by the analysis of the bond graph model topology.

Fault detection and fault isolation in the ground station

MILCOM 97 MILCOM 97 Proceedings, 2002
The satellite ground station environment is one in which the availability of the equipment is normally paramount. Satellite contacts may be scheduled at any time and the data being down-linked may be irreplaceable if the equipment in the ground station is not available to receive it.

Sliding mode observers for fault detection and isolation

Automatica, 2000
This paper considers the application of a particular sliding mode observer to the problem of fault detection and isolation. The novelty lies in the application of the equivalent output injection concept to explicitly reconstruct fault signals. Previous work in the area of fault detection using sliding mode observers has used disruption of the sliding ...

Robust Design of Fault Detection and Isolation Systems

Quality and Reliability Engineering International, 2006
AbstractInspired by the rationale of Robust Design, a novel methodology is presented for the design of diagnostic systems for fault detection and isolation (FDI). Detection/isolation capability and robustness, i.e. sensitivity to faults and insensitivity to noise, are addressed in an integrated way within a fully stochastic framework. Although FDI is a

Optimal threshold functions for fault detection and isolation

Proceedings of the 2003 American Control Conference, 2003., 2004
Fault diagnosis systems usually comprises two parts: a filtering part and a decision part, the latter typically based on threshold functions. In this paper, systematic ways to choose the threshold values are proposed. Two different test functions for the filtered signals are discussed and a method is described for determining the optimal threshold ...

A fault detection and isolation methodology

1981 20th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1981
A fault detection and isolation methodology has been developed for validation of sensors and plant components. Significantly, the isolation of most consistent and inconsistent subsets of measurements for the purposes of estimation and failure detection is performed on the basis of a multi-level, as opposed to the usual bi-level, fail/no fail ...
