Abstract
U ovom radu prikazane su osnove analize vladanja procesa, regulacijskog kruga i djelovanja regulatora. Objašnjene su osnovne metode vođenja procesa i ugađanja regulacijskih krugova. Na primjeru serijski povezanih procesa izmjene topline analizirani su temperaturni regulacijski krugovi, određeni su približni dinamički modeli i ugođeni parametri regulatora. Ispitano je vladanje regulacijskih krugova nakon ugađanja pri čemu je ustanovljena stabilna regulacija temperature bez značajnih oscilacija.This paper provides a theoretical basis on process dynamics analysis, control loops and controller performance. The methods of process control and control loop optimization are explained. In an example of heat exchange process, control loops were analyzed, their approximate dynamic models determined and controller parameters tuned. Control loop dynamics was studied after tuning and it was found that temperature control is stable without significant oscillations in process variables
