The method is framed in the context of model-based analytical redundancy, consisting in the generation of a residual signal by means of a diagnostic observer, for its posterior analysis. Once a fault has been detected, and assuming some basic a priori knowledge about the set of possible failures in the plant, the isolation task is then formulated as a type of on-line statistical classification problem. The proposed isolation scheme employs in parallel different hypotheses tests on a statistic of the residual signal, one test for each possible fault. This isolation method is characterized by deriving for the unidimensional case, a sufficient isolability condition as well as an upperbound of the probability of missed isolation. Simulation examples illustrate the applicability of the proposed scheme. date_type: published date: 2013-04 publication: Annual Reviews in Control volume: 37 number: 1 pagerange: 43-55 id_number: 10.1016/j.arcontrol.2013.03.002 institution: Telecomunicacion department: Matematica_Aplicada7 refereed: TRUE issn: 1367-5788 official_url: http://www.sciencedirect.com/science/article/pii/S1367578813000047 citation: Castillo López, Angela and Zufiria Zatarain, Pedro Jose (2013).
