Fault tolerant estimation of F-16 fighter dynamics against sensor faults
International Journal of Sustainable Aviation, 2016In this study the discrete nonlinear model of the F-16's flight dynamics and the estimation in real time of the aircraft states using extended Kalman filtering technique are investigated. The main topics of this study are fault tolerant estimation systems, which include the study of the robust Kalman filter, and the reconfigurable Kalman filter.

On sensor faults estimation using sliding mode observers
2010 Conference on Control and Fault-Tolerant Systems (SysTol), 2010This paper discusses the problem of designing the sliding-mode-based sensor faults estimation in a general structure suitable on the actuator as well as sensor faults detection and estimation. The problem addressed is indicated as an unified algebraic approach giving sufficient conditions of solution. Lyapunov inequality implying from two linear matrix

Fault Estimation of Switched Linear Systems with Actuator and Sensor Faults
2020This paper addresses the multiple fault estimation problem for the switched linear systems with actuator and sensor faults. By introducing an intermediate variable and augmenting state and sensor faults into a new vector, an fault estimation approach is proposed to contemporaneously estimate the state, the actuator and sensor faults.

Observer-based sensor fault estimation in nonlinear systems
Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2016Sensor bias faults and sensor gain faults are two important types of faults in sensor. Simultaneous estimation of these sensor faults in nonlinear systems in the presence of input disturbance and measurement noise is challenging and has not been adequately addressed in literature.

AbstractThis paper provided a robust strategy for controlling nonlinear interconnected large‐scale systems subject to a sensor fault. The inherent challenge in controlling such systems is to sustain robust closed‐loop stability and performance in nonlinear interactions, faults, and exogenous inputs.

Fault tolerant distributed estimation in wireless sensor networks
Journal of Network and Computer Applications, 2016In distributed wireless sensor networks (WSNs), each sensor node estimates the global parameter from the local data in distributed manner. An iterative distributed estimation algorithm is used where the diffusion co-operation scheme is incorporated. Presence of faulty sensor node in the network leads to inaccurate estimation in the conventional error ...

On fault tolerant estimation in sensor networks
2003 European Control Conference (ECC), 2003This paper addresses the fault tolerant estimation problem. Fault tolerance is defined with respect to a given estimation objective, namely a given functional of the system state should remain observable when sensor failures occur. Three criteria, which evaluate the system fault tolerance with respect to sensor failures when a reconfiguration strategy ...

Fragility estimates of smart structures with sensor faults
Smart Materials and Structures, 2013In this paper, the impact of sensor faults within smart structures is investigated using seismic fragility analysis techniques. Seismic fragility analysis is one of the methods used to evaluate the vulnerability of structural systems under a broad range of earthquake events.

Robust distributed estimation using efficient sensor-fault detection in sensor networks
2010 2nd International Symposium on Aware Computing, 2010A robust distributed estimation scheme for fusion center in the presence of sensor faults via collaborative sensor fault detection (CSFD) was proposed in our previous research [9]. The scheme can identify the faulty nodes efficiently and improve the accuracy of the estimates significantly.
