Generalized Luenberger observer-based fault-detection filter design: An industrial application

Abstract:

This paper presents a case study, where a failure detection filter and failure diagnosis based on the generalized Luenberger observer (GLO) are implemented. It is known that these types of observers use the output and the output derivatives of the observed system as its inputs. In some cases, the derivatives can cause false failure propagation, making diagnosis impossible. This study focuses on the GLO implementation using an industry example. (C) 2000 Elsevier Science Ltd.
