Abstract

Cilj ovog rada je projektiranje, izrada i upravljanje nastavne makete rotacijskog zamašnjaka. Realizirana nastavna maketa sastoji se od konstrukcijskih elemenata, upravljačkih komponenti, mjernih komponenti i programske podrške (Matlab / Simulink).
U zadatku je najprije bilo potrebno izraditi nastavnu maketu mehaničke konstrukcije zamašnjaka pogonjenog električnim motorom preko zupčanog prijenosnika. Zatim, izvesti matematički model sustava i simulirati njegovo ponašanje u programu Matlab Simulink te ugraditi komponente mjernog i upravljačkog dijela sustava na maketu. Potom, razmotriti moguće načine regulacije sustava, odabrati regulator i izvršiti simulaciju sustava. Naposljetku, bilo je potrebno provjeriti odabrani regulator eksperimentalno na nastavnoj maketi.
Sustav je najprije modeliran u programskom alatu SolidWorks, zatim je provjeren matematički model u Matlab Simulinku i nakon što su svi podaci bili zadovoljavajući, krenulo se na izradu makete. Regulacija sustava realizirana je korištenjem PI regulatora. Rezultati eksperimenata dokazuju primjenjivost nastavne makete u ispitivanju utjecaja pojedinih komponenti u mehaničkim sustavima.

Abstract (english)

The purpose of this study was designing, production and control of rotational flywheel. The realized model consists of constructional elements, control components, measuring components and software support.
In this work we had to create mechanical construction model of flywheel powered by electrical motor using a gear transmission. Mathematical model and simulation had to be tested in Matlab Simulink and components of measurement and control systems were added to the model. Various system control methods regulations were considered, the controller was chosen and system was simulated. In the end the chosen controller was experimentally tested on the educational setup.
The system was modeled in SolidWorks software and the mathematical model was tested in Matlab simulink programme. The model creation was started after all data was satisfactory. The flywheel speed was controlled using PI controller. The results of this experiment proved applicability of this model in testing of impact of components in mechanical system.
