Auxiliary signal design for robust failure detection: a case study

Recently an approach for multi-model identification and failure detection in the presence of model uncertainty and bounded energy noise over finite time intervals was introduced. This approach involved offline computation of an auxiliary signal and online application of the detection and identification test software has been developed to carry out this approach. This paper provides the first careful case study investigating a number of issues related to use of this software. Guidelines for users and suggestions for improvement are presented.
