Abstract

U ovom je radu realizirana maketa sustava za upravljanje protokom zraka. Najprije su, na temelju zahtjeva koje moraju ispuniti, odabrani elementi makete sustava: aktuatori, upravljački element sustava i senzor mjerenja protoka zraka. Zatim je modelirana zaklopka i ostale fizičke komponente koje s odabranim aktuatorima i senzorom čine maketu sustava. Konfigurirani su ulazno izlazni izvodi elektroničkog modula za upravljanje istosmjernim motorom odnosnom zaklopkom i ventilatorom te za komunikaciju sa senzorom protoka zraka. Naposljetku je izvršena sinteza regulatora zatvorenog kruga upravljanja. Regulatorom je, regulacijom položaja zaklopke, ostvaren brz i precizan odziv mjerene veličine protoka zraka s obzirom na promjenu referentne vrijednosti, ali i kompenzacija smetnje u sustavu nastale promjenom brzine vrtnje ventilatora.

Abstract (english)

In this thesis physical model of air flow management system is built. First of all, based on system requirements, elements of model are chosen: actuators, control element and air flow sensor. Designed damper and the rest of physical components, combined with chosen actuators and sensor, make physical model of the system. Input and output pins from microcontroller integrated circuit are configured for controlling the DC motor, which controls the damper, for the fan and for communication with the air flow sensor. Finally, synthesis of regulator in the closed loop system is made. With the regulator, by regulation of the damper position, fast and precise response is obtained from measured air flow considering change of the reference value. Likewise, compensation of the disturbance in system, made by change of fan speed, is accomplished.
