Redundancy Relations and Robust Failure Detection,

Abstract

All failure detection methods are based on the use of redundancy, that is on (possible dynamic) relations among the measured variables. Consequently the robustness of the failure detection process depends to a great degree on the reliability of the redundancy relations given the inevitable presence of model uncertainties. This paper addresses the problem of determining redundancy relations which are optimally robust in a sense which includes the major issues of importance in practical failure detection and which provides a significant amount of intuition concerning the geometry of robust failure detection.
