Abstract:
In this paper we deal with the observer based Fault Detection and Isolation problem. When this FDI problem is solvable with the existing sensors, we will classify these sensors according to their importance for the solvability of the considered FDI problem. The sensors will be classified into essential sensors, useless sensors and useful sensors. We tackle this problem when the system under consideration is structured, that is, the entries of the system matrices are either fixed zeros or free parameters. With such structured systems one can associate a graph. Simple algorithms allow to get from the graph the above sensor classification. Copyright © 2007 IFAC.
