Sensor Fault Detection, Isolation, and Accommodation Using Recurrent Neural Networks

Sensor is one of the vital parts in monitoring systems and control systems, it is im portant for these systems to work with more reliable sensor-data. In this paper, Intelligent sensor systems with fault detection, isolation,and accommodation have been constructed based on recurrent neural networks which fuse spatio-temposral information of the sensors. Recur- rent neural networks hold the abilities of modeling systems and predicting time-series data with excellent performance. The results of simulation are given to show that the smart sensor sys- tem can validate the sensor values and recover the fault sensors' signals.
