diplomsko delo
Povzetek
V diplomskem delu sta predstavljeni simulacijska platforma MicroLabBox za izvajanje
simulacij v realnem času z možnostjo vključitve strojne opreme v simulacijski krog ter
aplikacija za merjenje B-H ali Ψ-I karakteristik vzorcev materiala oziroma drugih poljubnih
elektromagnetnih struktur. V prvem delu so predstavljene značilnosti sistema. Sledi jim
predstavitev glavnih korakov izdelave projekta, kjer so razvidne vloge programov Matlab,
Simulink in ControlDesk, ki so uporabljeni pri izdelavi. Prva dva omogočata izdelavo
aplikacije, tretji pa služi kot grafični vmesnik. V zadnjem poglavju je v okviru
eksperimentalnega dela predstavljena priprava merilnega mesta B-H karakteristik. Merilna
metoda temelji na transformatorski inducirani napetosti. MicroLabBox generira sinusno
napetost želene frekvence, ki preko ojačevalnika magneti jedro ter hkrati zajema podatke o
časovnih potekih magnetilnega toka in inducirane napetosti, iz katerih določi vrednosti gostote magnetnega pretoka in magnetne poljske jakosti. Z njimi se v grafičnem vmesniku izrisuje histerezna zanka ter izračunavajo izgube magnetenja. Za demonstracijo delovanja so bile izvedene meritve, katerih rezultati so podani v zadnjem delu diplomskega dela.

This diploma thesis presents MicroLabBox – a simulation platform for real-time applications
with the ability to include hardware in the simulation loop and the preparation of a system for measuring magnetic hysteresis loops. At the beginning of the thesis key features of the system are introduced. They are followed by a presentation of the main steps of creating a project in which the roles of programs Matlab, Simulink and ControlDesk are shown more clearly. The first two are used for creating a model and the third one is used as a graphical interface. In the last chapter, which is the experimental part of the work, the preparation of the measuring system is presented. The measurement method is based on transformer induced voltage. MicroLabBox is used to generate a sinusoidal voltage of desired frequency. With the use of an amplifier, it magnetizes the ferromagnetic core and simultaneously records magnetizing current and induced voltage. Recorded signals are needed to calculate magnetic flux density and magnetic field strength in the function of time. With them, the magnetic hysteresis loop is plotted in a graphical interface unit and magnetic iron losses are calculated. For a demonstration of the developed application different measurements of magnetic core losses were performed and recorded. The results are presented in the last part of the thesis. |
