The aim of this work is to describe the kinetics of yogurt starter culture production by S.thermophilus 13ɚ and Lb. bulgaricus 2-11 and to quantitatively analyse the effect of different dissolved oxygen concentration in the milk on the process trend. Five different mathematical models for description of process kinetics are tested and the best one is(More)
In the present paper on-line action-dependent heuristic neuro-dynamic programming was applied for optimization of a complex nonlinear production process. The approach is based on recurrent neural network architecture — Echo state network (ESN) — as critic network within the frame of adaptive critic design (ACD) scheme. The subject for(More)
The present paper presents a hybrid model of yogurt starter mixed culture fermentation. The main nonlinearities within a classical structure of continuous process model are replaced by neural networks. The new hybrid model accounts for the dependence of the two microorganisms' kinetics from the on-line measured characteristics of the culture medium – pH.(More)
