Abstract:Osnovni namen diplomskega dela je bil s pomočjo demonstracijske naprave za regulacijo pretoka RT 624 testirati in preučiti različne vrste regulacije in jih med seboj primerjati, ter tako ugotoviti, katera izmed možnih regulacij je najboljša. Izvajali smo povratno-zančno regulacijo s pomočjo pretočnega senzorja in avtomatskega ventila. V prvem delu diplomskega dela smo določevali območje linearnosti avtomatskega ventila. Glede na to območje smo nato izvedli stopničasto spremembo, na osnovi katere smo določili potrebne parametre za proporcionalno, proporcionalno-integrirno ter proporcionalno-integrirno-diferencirno regulacijo. S pomočjo izračunanih parametrov smo testirali ustreznost teh parametrov pri različnih vrstah regulacije in opazovali odziv sistema. Ukvarjali smo se s servo problemom, kjer sistem sledi referenčni vrednosti ter z regulacijskim problemom, kjer sistem odpravlja motnjo pri konstantni referenčni vrednosti. Pri tem smo opazovali čas, v katerem je doseženo novo stacionarno stanje oziroma čas, v katerem je odpravljena motnja. Pozorni smo bili tudi na stabilnost sistema, torej če sistem oscilira in ali se sistem odzove s preletom. Da bi se še bolj približali idealnemu odzivu sistema smo parametre za regulacijo določevali še s poskušanjem. Ugotovili smo, da je najboljša proporcionalno-integrirno-diferencirna regulacija. V določenih primerih smo se idealnemu odzivu sistema najbolj približali, ko smo parametre nastavili s poskušanjem. Lahko pa rečemo, da so parametri za regulacijo, ki so dobljeni v skladu s stopničasto spremembo, v nekaterih primerih zelo dober približek idealnemu odzivu sistema.

Title:Control of a liquid flow system using flow sensor, automatic valve and feedback control
Abstract:The main goal of the thesis was to test and study flow-control by using the demonstration device RT 624 and compare different controller types against each other in order to assess which one is the best. We performed feedback control using an automatic electric valve. In the first part of the thesis, we determined the linearity range of the automatic valve. With respect to this, we then performed a step change by means of which we determined the necessary parameters for a proportional, proportional-integrated, and proportional-integrated-differentiated control. By means of calculated parameters, we tested the appropriateness of these parameters in various kinds of control and observed the response of the system. We dealt with the servo problem where the system follows a reference value and with the regulator problem, where the system eliminates the disturbance. We monitored the time in which a new stationary state is achieved and the time in which disturbance is eliminated. We were attentive about the stability of the system, i.e. if the system oscillates and/or if the system responds with an overshoot. In order to approximate to the ideal response of the system, we determined the parameters for control also by trial and error. We ascertained that proportional-integrated-differentiated control is the best. We approximated to the ideal response of the system the most when we set the parameters by trying. We can say, however, that in some cases, the parameters for the control which were achieved in accordance with the step change are a very good approximation to the ideal response of the system.
