چکیده مقاله:
In this paper, two different sensor fault detection methods for federated filter structure are proposed. In the first method, measurement residual of local filters in federated noreset mode filter configuration is monitored. In the second technique, a moving window principal component analysis (MWPCA) is investigated on measurement residual of localfilters outputs. Faults which are regarded in this paper include soft, hard and delta. To verify the efficiency of the proposed faultdetection methods in federated filter structures, an integrated vehicular navigation system is used as a case study. Simulationresults show the effectiveness and accuracy of MWPCA method with respect to measurement residual in fault detection anddecreasing false alarms in federated filter structures.
