Distributed State Estimation for Heterogeneous Mobile Sensor Networks with Sensor Faults

2019 Chinese Control Conference (CCC), 2019
Consensus-based distributed state estimation for homogeneous mobile sensor networks has been widely studied currently. However, the sensors used for target detection and tracking in practical applications usually have different physical properties, different measuring range or accuracy.

Combining channel estimation and sensor fault protection in wireless sensor networks

2011 8th International Conference on Information, Communications & Signal Processing, 2011
The ongoing development of wireless sensor networks (WSNs) demands not only low-power sensors and less system cost but also good performance. Considering this background, investigating a new technology to satisfy both requirements is an important issue for current development of wireless sensor network systems.

Integrated design of robust fault estimation and fault‐tolerant control against simultaneous actuator and sensor faults

Asian Journal of Control, 2019
AbstractThis paper investigates the problems of simultaneous actuator and sensor faults estimation, as well as the fault‐tolerant control scheme for a class of linear continuous‐time systems subject to external disturbances. First, the original system is transformed into a singular form by extending the actuator fault and sensor fault to be parts of ...

Fault Estimation in Finite Frequency Domain for Uncertain Systems with Sensor Fault

2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2018
Ahstract- This paper addresses the problem of sensor failure fault estimation for continuous linear uncertain systems with sensor failure fault, which belongs to multiplicative faults, and this problem has not been well investigated in the literature. With the aid of generalised KYP lemma, three finite frequency performance indexes are given to measure

Fault diagnosis and estimation for near-space hypersonic vehicle with sensor faults

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2011
This paper addresses a practical issue in fault diagnosis and estimation for a near-space hypersonic vehicle (NSHV) with sensor faults. First, the Takagi–Sugeno (T–S) fuzzy model is established to represent the NSHV non-linear dynamics, and sliding mode observers (SMO) are designed to generate a bank of residuals.

Fault Estimation and Fault Map Construction on Cluster-based Wireless Sensor Network

IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing - Vol 2 - Workshops, 2006
Most applications of Wireless Sensor Networks (WSNs) the sensors are deployed on unfavorable environment such as chemical reactor or battlefield that with high temperature, noise, and interference, could probably incur sensor nodes sense, compute, or communicate improperly. Those also raise error responds to the data collectors.

Aircraft sensor fault detection using state and input estimation

2016 American Control Conference (ACC), 2016
This paper presents a method for detecting aircraft sensor faults using state and input estimation. We formulate the kinematics as a nonlinear state space system, which requires no modeling information, and thus is applicable to all aircraft. To illustrate the method, we investigate three fault-detection scenarios, namely, faulty pitot tube, angle-of ...

Sensor fault estimation and compensation for hybrid switched system

2016 20th International Conference on System Theory, Control and Computing (ICSTCC), 2016
In this paper, we proposed a new way that allows the identification and the compensation of sensor fault at the same time for hybrid switched systems. Indeed, to compensate this fault we chose the additive fault tolerant control (FTC). The synthesis of this FTC requires two important stages.

Fault-Tolerant Control and Adaptive Estimation Schemes for Sensors with Bounded Faults

2007 IEEE 22nd International Symposium on Intelligent Control, 2007
A novel structure of the state observer with adaptive estimation scheme of sensors and the design of control law to accommodate sensor faults are presented. In this novel approach, based on Lyapunov method, the system is designed, in its feedback loop, to achieve good estimation of the plant states and to adaptively monitor the condition of sensors ...
