Fault detection and isolation for uncertain systems
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2004The goal of this paper is to extend the fault detection procedure for MIMO system in order to isolate an anomaly once its presence detected, while insisting on the difficulties encountered within the framework of the set-membership approach. The proposed method is presented initially to deal with the case where only one fault may affect the system at a

Fault detection and isolation in nonlinear systems
Annual Reviews in Control, 2009Abstract This paper deals with fault detection and identification in dynamic systems when the system dynamics can be modeled by smooth nonlinear differential equations including affine, bilinear or linear parameter varying (LPV) systems. Two basic approaches will be considered, these apply differential algebraic and differential geometric tools.

Fault detection and isolation in nonlinear systems
1999 European Control Conference (ECC), 1999In 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 of Actuator Faults in Overactuated Systems
2007 American Control Conference, 2007This paper investigates development of fault detection and isolation (FDI) filters for overactuated systems. Due to input channels coupling effects and dependencies in overactuated systems, the necessary condition for applying geometric FDI approaches is not satisfied. In this work a geometric FDI approach for linear systems is extended to overactuated

Fault detection and fault isolation in the ground station
MILCOM 97 MILCOM 97 Proceedings, 2002The 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.

Fault Detection and Isolation for State Affine Systems
European Journal of Control, 1998The 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, 2000The 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, 2004This 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.

Robust Design of Fault Detection and Isolation Systems
Quality and Reliability Engineering International, 2006AbstractInspired 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
