The growth rates of the micro-organisms in bioreactors are described by complex kinetic expressions, and the modeling and estimation of such kinetics are essential for the design of control strategies. This paper deals with the on-line estimation of kinetic rates of a baker's yeast process, taking place inside a Fed-batch Bioreactor. This bioprocess is widely used in bioindustry; its model is highly...
This paper deals with the analysis of a nonlinear dynamical model of a class of bioprocesses. Some structural properties are widely discussed, such as the partition of the model in a linear part and a nonlinear term, the decoupling of the kinetics, the positivity of the model. Also, the singular perturbations method and quasi-steady state assumption are used in order to obtain reduced order models,...
This paper deals with the problem of on-line estimation of kinetic rates inside biological sequencing batch reactors (SBRs). Two wastewater treatment bioprocesses that are carried out inside SBRs are taken into consideration. These biotechnological processes are highly nonlinear and, furthermore, the available on-line measurements are lack and the reaction kinetics is not perfectly known. The unknown...
