Fault Diagnosis of Linear Systems Based on Parameter Estimation and Statistical Method

파라미터추정과 통계적방법에 의한 선형 시스템의 고장진단

In this paper we propose an FDI(fault detection and isolation) algorithm to detect and isolate single faults in linear systems. When a change in the system occurs the errors between the system output and the estimated output cross a threshold, and once a fault in the system is detected, the FCFM statistically isolates the fault by using the error between each neural network based fault model output and the system output.
