Resumen: Biotechnological processes represent a challenge into the
control field, due to its high non linearity. Particularly,
continuous alcoholic fermentation by Zymomonas mobilis
presents high ethanol performance, but it shows highly
oscillatory behaviour in process variables, because of the
influence of inhibition dynamics (rate of ethanol
concentration Z and I) over Biomass, Substrate and
Product concentrations; it is a significant challenge from
the control perspective. In this work, a new and
significant solution for control of biotechnological
variables into the fermentation process, based on
numerical methods and linear algebra is proposed. This
methodology, allows developing the controller design
through the use of dynamic analysis and without the use
of complex calculations.
