Abstract

U ovom radu opisuje se izrada toplinske komore i snimanje njezine prijelazne karakteristike u svrhu određivanja parametara modela procesa, te se na osnovi tih rezultata implementira odgovarajući regulator temperature. Iz snimljene karakteristike procesa utvrđeno je da se dinamika procesa može opisati dinamičkim modelom proporcionalnog člana s jednom vremenskom konstantom (PT1 modelom), te je za njegovu regulaciju dovoljan PI regulator temperature. Na osnovi eksperimentalno identificiranog modela procesa, u programskom paketu Matlab/Simulink je napravljena simulacija regulacije temperature toplinske komore, kao priprema za kasniju implementaciju na laboratorijskom postavu s upravljačkim sklopovljem tvrtke Mitsubishi Electric, to jest u programibilnom logičkom kontroleru (PLC-u) FX5U-32MT/ESS uz praćenje stanja putem grafičkog operaterskog terminala (HMI-a) GS2107-WTBD. Plan je da se projektirani sustav koristi u edukaciji sadašnjih i budućih studenata na području digitalne regulacije kroz laboratorijske vježbe.

Abstract (english)

This work describes the design of the heat chamber and the recording of process step response for the purpose of determining process parameters, and subsequent implementation of an appropriate temperature controller. From the recorded process step response it is determined that the process dynamics can be described by a first-order lag term (PT1 model), for which a simple PI controller may be used. Based on the experimentally-identified process model, a temperature control system simulation model of the particular heat chamber has been built within Matlab/Simulink in preparation for subsequent implementation on the laboratoty experimental setup. It is anticipated that the experimental control system implementation will be based on the Mitsubishi Electric control system kit, more precisely on the FX5U-32MT / ESS programmable logic controller (PLC) with process flow is monitoring based on GS2107-WTBD graphic operator terminal (HMI). It is planned to utilize the designed system for the purpose of education of current and future students in the field of digital control through laboratory exercises.
