FAULT DETECTION BASED ON SET-MEMBERSHIP INVERSION

This paper deals with a set-membership method for fault detection. Based on interval analysis, the proposed approach focuses on the design of consistency tests for dynamical systems with additive and multiplicative parameter uncertainties. Instead of canceling uncertainties following the example of the so-called robust approaches, uncertain analytical redundancy relations take uncertainties into account as bounded variables. The use of a set-membership inversion method allows non-linear analytical redundancy relations to be directly processed without requiring any linearization.
