| Abstract [eng] |
This work examines the growth process of microbial cultures, which is crucial in both industry and science, and is associated with the production of biological materials such as enzymes and antibiotics. The primary focus is on the regulation of the relative growth rate of biomass in periodically fed microbial cultures, where growth materials are supplied at specific time intervals. The study investigates two control methods - a neural controller and a PI regulator. The aim of the work is to develop and investigate a neural controller algorithm for managing the feed flow rate, thereby altering the growth rate of the biomass. The work is divided into three parts, describing the biotechnological process, creating and explaining the PI regulator and the neural controller. Trials are carried out with various initial parameters in the presence of noise. Results are evaluated based on the obtained graphs and calculated errors. |
