Abstract

U sklopu diplomskog rada, proveden je projekt revitalizacije postojećeg zračnog tunela. Konkretnije, naglasak je stavljen na razvoj upravljačkog dijela sustava dvo-osnog rotacijskog posmičnog prigona koji će se koristiti za precizno pozicioniranje modela letjelice u mjernoj sekciji zračnog tunela. Središnji dio upravljačkog sustava je softver otvorene arhitekture LinuxCNC. Komunikacija između NC računala i ostalih dijelova sustava ostvarena je korištenjem EtherCAT sabirnice. EtherCAT tehnologija je, zajedno s LinuxCNC-om, detaljno opisana u teorijskom dijelu rada. U nastavku je proveden proces odabira elemenata upravljačkog elektro-ormara, te su nacrtane pripadajuće električne sheme. Nakon uspješne integracije svih elemenata upravljačkog sustava, obavljeno je početno parametriranje LinuxCNC softvera i servo regulatora. Konačno, posmični prigoni su testirani te je provedeno podešavanje parametara regulacijskih petlji.

Abstract (english)

In this thesis, a project of revitalization of existing wind tunnel was undertaken. More specifically, the focus was put on the development of the control system for two-axis rotary feed drive which will be used for precise positioning of the aircraft model inside the test section of the wind tunnel. The central part of the designed control system is open architecture machine controller, LinuxCNC. Communication between NC computer and different parts of the system was realized using EtherCAT fieldbus system. EtherCAT technology is, along with LinuxCNC, described in detail in the theoretical part of the thesis. Furthermore, a process of selecting control cabinet elements was conducted and corresponding electrical schemes were drawn. After successful integration of all the control system elements, initial commissioning of LinuxCNC software and servo drives was carried out. Finally, feed drives were tested andtuning of control loops was performed.
