Abstract: This paper presents an overview of recent results of some state observers for a class of non-linear exothermic fed-batch chemical reactors. The proposed techniques deal with kinetics and heat transfer uncertainties which are frequently encountered in fed-batch processes. The presentation of the different approaches is organised by following the level of knowledge with respect to each kind of uncertainties.
Keywords: fed-batch reactors; state observers; state estimation; online calorimetry; nonlinear systems; kinetics; heat transfer; uncertainties.
