Robust analysis of multi-sensor architecture fault detection and investigation of pseudo sensor enhancement method (PSEM)

Abstract

The recent technology of intelligent systems have been used multiple sensors to assess real-time information of the internal system states and the environmental operating conditions. In case of sensor (s) transient fault, the disconnection of the readings caused to apply inappropriate actions. So, the needs for sensor fault detecting and estimating multiple sensor faults become an important process to optimize and enhance the system performance. In this paper, a robust analysis of multi-sensor architecture fault detection has been introduced to study different arrangement sensors architecture and detect the transient fault of each sensor. Then, a pseudo sensor enhancement method (PSEM) has been presented and investigated. The simulation results of different sensor architecture configurations without and with applying the PSEM have been introduced and analyzed to demonstrate the performance of the proposed method to meet the requirements for multiple sensor intelligent systems.
