Implementation of Stir-Speed Adopted Controllers Onto a Batch Bioreactor for Improved Fermentation

Quality, quantity, and economy of the fermentation product depend on transient response steady-state process. Due to its simple construction, an industrial batch bioreactor cannot be equipped with a closed-loop control system that applies adding or removing substances during fermentation. This theoretical practical study displays how can controlled, in this case by altering rotational speed stirrer such bioreactor. A numerical analysis was employed set up mathematical model describes impact The consists linear non-linear parts. To determine their parameters, least square identification particle swarm optimization method were utilized. fitted tested experimentally laboratory operating design synthesis conventional advanced reference adaptive system, which is also convenient for controlled plants, carried out based determined model. Both concepts first implemented into dSpace 1103 faster development prototyping. Finally, they realized Siemens SIMATIC S7 programmable logic controller, ideal environment operation. During operation bioreactor, systems along acquisition measured data involving CO2 concentration product. findings successfully applying controllers milk are analyzed presented.
