Simulated dynamics and control of an extractive alcoholic fermentation

In this study, we investigated the dynamics of a computer simulation of a c ontinuous alcoholic fermentation process combined with a flash column under vacuum. The alcohol was partially extracted in order to maintain its conce ntration at about 40 kg/m(3) in the fermenter. The mathematical model of th e fermentation was developed for industrial conditions and considers the ef fect of the temperature on the kinetic parameters. The performance of the d ynamic matrix control algorithm, single input single output and multiple in put multiple output, for the control of the extractive process was studied. The concerts of factorial design were used in a simulation study to determ ine the best control structures for the process.
