Design of Observer Based Crack Detection Filters and Their Application to Crack Detection and Isolation

摘要

In this paper the notion of a crack detection filter is introduced and algorithms forthe design of such filters presented. The concept is based on the design of observersthat sensitive or insensitive to the presence of a crack in a structure. It arises froman application of fault detection filters to structures with cracks and is a novel andnew concept. The feasibility of designing crack detection filters for structural healthmonitoring applications is then demonstrated.
