Paper Abstract

This paper introduces a technique for non-destructive, real-time health monitoring using a model-based observer to determine the onset and location of unintended changes in a structure. These changes could be caused by slipping in joints or latches in deployed structures, or by damage to structural components. An algorithm for calculating the observer feedback gains which allow localization of these changes is described. The algorithm is based on ideas from noninteracting control theory. The validity of the technique is demonstrated by applying it to a computer model of a structure.
