A Multi-agent Architecture for Sensors and Actuators' Fault Detection and Isolation in Case of Uncertain Parameter Systems

In this work, a multi-agent system for fault detection and isolation is proposed in case of faults affecting sensors and actuators of bond graph modelled uncertain parameter systems. The diagnostic system is composed of different agents cooperating and communicating through messages exchange. each agent is specialized in a specific task of the diagnosis process. Detection and isolation routines arc based on residuals processing. Residuals are obtained from bond graph model. To illustrate our approach. a hydraulic system in case of 5% of uncertainties is simulated under Matlab/Simulink environment. The diagnostic system is implemented in JADE environment and has shown good detection and isolation results.
