Sensors used in the monitoring of machinery with the object of identifying faults are usually related to the dentification of physical and/or chemical changes. As a consequence, sensors are frequently similar to those employed for control purposes and, indeed, there is a considerable similarity between the two techniques.

Fault-tolerant decision fusion via collaborative sensor fault detection in wireless sensor networks
IEEE Transactions on Wireless Communications, 2008This work addresses fault-tolerant distributed decision fusion in the presence of sensor faults when local sensors sequentially send their local decisions to a fusion center. This work also proposes a collaborative sensor fault detection (CSFD) scheme for eliminating unreliable local decisions when performing distributed decision fusion. In particular,

This work proposes a sensor fault isolation scheme for co-existence of permanent magnet synchronous machine (PMSM) current sensor and non-sensor imbalance faults. The proposed method examines DC link battery current residuals to determine the location of machine current sensor and non-sensor imbalance faults.

In this chapter, a NN-based and EKF-based sensor fault detection and accommodation (SFDA) scheme are proposed and compared under different levels of unknown inputs and fault types. The schemes are tested on a nonlinear UAV model. The EKF is chosen as a representative of nonlinear (fixed) modelbased SFDA schemes which rely on a mathematical description ...

Fault Aware Wireless Sensor Networks
2007 IEEE International Conference on Networking, Sensing and Control, 2007Wireless Sensor Networks (WSNs) collect information about the physical environment aiding to a wide variety of applications ranging from target detection to monitoring of harmful chemical gases. The drive to scale down the system size and cost has resulted in constraints in the quality of components.

Reconstruction of Sensor Faults
2011This chapter will focus specifically on sensor faults. Different formulations will be considered in which the measured output signals are filtered to yield ‘fictitious systems’ in which sensor faults appear as ‘actuator faults’. Consequently, the actuator fault reconstruction ideas from the previous chapters can be applied to the fictitious system to ...

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.

Sensor Optimal Configuration Method for Sensor Fault Detection
2020 Chinese Automation Congress (CAC), 2020For the limited number of sensors, an optimized sensor configuration method for sensor fault detection is proposed. By defining the concept of the sensor information redundancy and its measurement, the performance evaluation criteria for different configuration modes are given, and a sensor optimal placement strategy for ensuring maximum information ...
