| Abstract: | In the chapter, milk fermentation for kefir production is studied. The traditional
kefir production process based on inoculating kefir grains into milk is considered. The
quality and quantity of the produced kefir also depend on the dynamics of the fermentation process. The chapter presents the design and synthesis of the closed-loop
control system in which changing the bioreactor’s temperature is used to control the
time course of the concentration of dissolved CO2. In the chapter: (1) a nonlinear
dynamic mathematical model of the fermentation process, which allows evaluating
the influence of the bioreactor’s temperature on the dynamics of the fermentation
process, is presented; (2) the design and synthesis of a conventional linear control
system with constant parameters are carried out; (3) an adaptive control system that
enables the tracking of the courses of the quantities of the fermentation process to the
desired reference trajectories without the time-consuming preliminary identification
of the parameters of the fermentation process model is developed. The numerical,
experimental, and analytic outcomes of the study are presented. |
