This paper presents a novel method for assessing multi-fault diagnosability and detectability of non linear parametrized dynamical models. This method is based on computer algebra algorithms which return precomputed values of algebraic expressions characterizing the presence of some multi-fault(s). Estimations of these expressions, obtained from inputs and outputs measurements, permit then the detection and the isolation of multi-faults possibly acting on the system. This method applied on a coupled water-tank model attests the relevance of the suggested approach. 查看全文>>
