Sensor Placement for Fault Diagnosis
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2008An algorithm is developed for computing which sensors to add to meet a diagnosis requirement specification concerning fault detectability and fault isolability. The method is based only on the structural information in a model, which means that possibly large and nonlinear differential-algebraic models can be handled in an efficient manner.

Isolability of faults in sensor fault diagnosis
Mechanical Systems and Signal Processing, 2011Abstract A major concern with fault detection and isolation (FDI) methods is their robustness with respect to noise and modeling uncertainties. With this in mind, several approaches have been proposed to minimize the vulnerability of FDI methods to these uncertainties.

Distributed fault-tolerant detection via sensor fault detection in sensor networks
2007 10th International Conference on Information Fusion, 2007This work addresses the design of a distributed fault-tolerant decision fusion in the presence of sensor faults when the local sensors sequentially send their decisions to a fusion center. A collaborative sensor fault detection (CSFD) scheme is proposed here to eliminate unreliable local decisions when performing distributed decision fusion.

Fault-tolerant system for catastrophic faults in AMR sensors
2015 IEEE 21st International On-Line Testing Symposium (IOLTS), 2015Anisotropic Magnetoresistance angle sensors are widely used in automotive applications considered to be safety-critical applications. Therefore dependability is an important requirement and fault-tolerant strategies must be used to guarantee the correct operation of the sensors even in case of failures.

Active Fault-Tolerant Control for a Quadrotor with Sensor Faults
Journal of Intelligent & Robotic Systems, 2017An active fault-tolerant control scheme for a quadrotor with velocity sensor faults is presented in this paper. A two-level control scheme is designed to guarantee the quadrotor to track the given trajectory in case of no faults. The control scheme consists of an external-loop Proportion Differentiation (PD) control law and an internal-loop Proportion ...

Fault Tolerant Control of EPS System with Sensor Fault
Journal of Circuits, Systems and Computers, 2019Taking into account the sensors faults, modeling of electric power steering (EPS) behavior improves steering reliability. Such task becomes difficult considering the nonlinearity of EPS systems. Therefore, in order to ensure the good behavior stability of the EPS, it is important to validate such established models on a real system.

Fault Tolerance for Islandable-Microgrid Sensors
2021 IEEE International Symposium on Defect and Fault Tolerance in VLSI and Nanotechnology Systems (DFT), 2021This paper presents defect tolerance strategies for islandable-microgrid sensors both at the sensor level and at the matrix (or deployment) level. A microgrid is a group of interconnected distributed power/energy sources and loads with well-defined electrical boundaries that act as a single controllable entity with respect to the main grid or other ...

Decentralized fault diagnosis for sensor networks
2009 IEEE International Conference on Automation Science and Engineering, 2009In this paper we study the problem of fault diagnosis for sensor networks.We examine faults that involve an anomalous behavior of the sensor and investigate their diagnosis only through the local interaction between faulty nodes and healthy ones. We provide heuristics to actively diagnose faults and recover the nominal behavior.

Proceedings of the 2003 American Control Conference, 2003., 2004
Current sensor FDIR (fault detection, isolation, & recovery) generally focuses on sensor bias and drift anomalies, which require models. However, dead sensors and excessive noise faults are more common in practice. The latter two faults are interesting in that they can be detected using only the measurements from each sensor.

A Taxonomy of Faults for Wireless Sensor Networks
Journal of Network and Systems Management, 2017Over the last decade, Wireless Sensor Networks (WSN) went from being a promising technology to the main enabler of countless Internet of Things applications in all types of areas. In industry, WSNs are now used for monitoring and controlling industrial processes, with the benefits of low installation costs, self-organization, self-configuration, and ...
