Abstract (Croatian)

U ovom završnom radu načinjen je eksperiment regulacije sile hidrauličke preše pomoću programa LabVIEW i uređaja NI myRIO. LabVIEW je grafički programski jezik namijenjen lakšem sakupljanju podataka iz ljudske okoline sa raznih instrumenata. Najčešće se koristi za prikupljanje, analizu i obradu podataka te kontrolu instrumenata i opreme. Programi rađeni pomoću LabVIEW alata nazivaju se Virtualni Instrumenti, skraćeno VI (engl. Virtual Instruments), jer njihov izgled i rad imitira stvarne instrumente. Svaki VI se sastoji od prednjeg panela i blok dijagrama. Prednji panel (engl. Front panel) namijenjen je za izradu grafičkog sučelja koji korisnik vidi kada je sustav pokrenut, a blok dijagram (engl. Block diagram) sadrži programske elemente preko kojih se odvija obrada podataka. S elektro-hidrauličkim servo sustavom povezan je uređaj NI myRIO na kojem se izvršava upravljački program za regulaciju sile hidrauličke preše primjenom servo ventila. NI myRIO je laboratorijski uređaj koji omogućuje izvršavanje algoritma u stvarnom realnom vremenu. Za vizualizaciju i nadzor rada elektro-hidrauličkog servo sustava koristi se prijenosno računalo na kojem se nalazi grafičko sučelje.

Abstract

In this final thesis an experiment of hydraulic press force control using LabVIEW program and NI myRIO device has been made. LabVIEW is a graphical programming language designed to facilitate the collection of human-environment data from various instruments. It is most commonly used for data acquisition, analysis and processing, as well as for instrument and equipment control. Programs built in LabVIEW are called VIs (Virtual Instruments) because their appearance and operation imitate physical instruments. Every VI is composed of Front Panel and Block Diagram. Front panel is intended for creating a graphical interface that the user can see when the system is running, while block diagram contains program elements through which data processing takes place. An electro-hydraulic servo system is connected to the NI myRIO device, where a hydraulic press force control is performed using the servo valve. NI myRIO is a laboratory device that enables real-time algorithm execution. A computer with a graphical interface is used to visualize and monitor the work of the electro-hydraulic servo system.
