| Popis: | International audience; This paper deals with sensor and process fault detection , isolation (FDI) and identification of an intensified heat-exchanger/reactor. Extended high gain observers are adopted for identifying sensor faults and guaranteeing accurate dynamics since they can simultaneously estimate both states and uncertain parameters. Uncertain parameters involve overall heat transfer coefficient in this paper. Meanwhile, in the proposed algorithm, an extended high gain observer is fed by only one measurement. In this way, observers are allowed to act as soft sensors to yield healthy virtual measures for faulty physical sensors. Then, healthy measurements , together with a bank of parameter interval filters are processed, aimed at isolating process faults and identifying faulty values. Effectiveness of the proposed approach is demonstrated on an intensified heat-exchanger/ reactor developed by the |
