Online Steady State Detection and Isolation of Fault Measurements Occurred by Sensors and Actuator

The purpose of this paper is the online steady state detection and isolation of fault measurement occurred by sensors and actuator. The used approach is an analytical method that based on linear state space description of the system. It used the measurements provided by sensors to calculate the residuals. The later are compared to zero in order to detect the faults. After that they will be analyzed in order to identify which element (actuator or speed sensor or current sensor) affected by the fault. The proposed approach is applicated on DC motor. The experimental set up based on using DSpace card with its environments shows that the aim of this work is achieved successfully.
