Fault detection based on set theoretic methods and connexions with fault tolerant control

We proposed a set-theoretic fault detection mechanism for multisensor systems with a classification of possible functioning according to the use in the feedback mechanism. The healthy, faulty and under-recovery class are characterized via set descriptions in the residual space and as such can be monitored via on-line mechanisms [26] . Furthermore, the robust detection has been enhanced with an interval observer mechanism for the monitorig during the transients [28] .
