A fault detection and isolation methodology
1981 20th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1981A 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 ...

Fault Tolerant Control and Fault Detection and Isolation
2011This chapter formally provides a definition of the terms fault and failure and briefly discusses the different types of faults and failures which can occur in actuators and sensors—with specific aircraft examples. The chapter introduces the concept of fault tolerant control and gives a general overview of the different FTC and FDI research fields.

Fault detection and isolation observers
International Journal of Control, 1994A design of reduced-order observers is proposed for linear time-invariant systems with unknown inputs including unknown measurement disturbances. Based on the unknown-input observer design, a systematic treatment of designing fault detection and isolation (FDI) observers is provided.

Fault Detection and Isolation of Actuator Faults in Spacecraft Formation Flight
Proceedings of the 45th IEEE Conference on Decision and Control, 2006This paper investigates the development of Fault Detection and Isolation (FDI) filters for spacecraft formation flight. A MIMO architecture for formation flying control is considered. By utilizing a geometric FDI methodology, a local/decentralized detection filter is developed for detecting faults in other spacecraft by determining the required ...

Synthesis of Fault Detection and Isolation Filters
2017This chapter presents general synthesis procedures of fault detection filters, which solve the fault detection problems formulated in Chap. 3. Two computational paradigms are instrumental in developing generally applicable, numerically reliable and computationally efficient synthesis methods.

Fault Detection and Isolation for Affine Fuzzy Systems With Sensor Faults
IEEE Transactions on Fuzzy Systems, 2016This paper investigates the fault detection and isolation (FDI) problem for a class of nonlinear systems with sensor outage faults. The considered nonlinear systems are described as affine fuzzy models, and the system outputs are chosen as the premise variables of fuzzy models.

Performance metrics for fault detection and isolation filters
Proceedings of the 2011 American Control Conference, 2011Fault detection and isolation (FDI) filters are typically synthesized for open-loop or closed-loop systems. The controller affects the FDI filter performance in the closed-loop. Performance metrics for FDI filters are proposed to assess filter performance and controller-filter interaction in the presence of uncertain dynamics in the closed-loop.

A toolbox for model-based fault detection and isolation
1999 European Control Conference (ECC), 1999A toolbox for model-based fault detection and isolation (FDI) has been developed in the MATLAB/SIMULINK environment. It includes methods relying on analytical or qualitative models of the supervised process. A demonstration of each approach can be performed on a simulation of either a three-tank system, a cocurrent or a countercurrent heat exchanger ...

Actuator fault detection and isolation system for an hexacopter
2014 IEEE/ASME 10th International Conference on Mechatronic and Embedded Systems and Applications (MESA), 2014The problem of detection and isolation of actuator faults in hexacopter vehicles is address in this article. The aim is to detect and isolate possible faults which can occur on the vehicle actuation system (i.e. rotors and propellers). The dynamic nonlinear model of an hexarotor vehicle is first derived to build a model-based diagnosis system.

Detection and Isolation of Multiplicative Faults
2020The previous chapters are mainly dedicated to the diagnosis issues of additive faults. Even if further efforts are needed to develop novel methods to deal with this class of faults more efficiently, it is the common opinion that the framework of diagnosing additive faults is well established.
