Abstract

Diplomski rad sadržava detaljan teoretski opis stroja za hladno valjanje čelične trake s opisom korištenih funkcija upravljanja i programskog dijela s opisom korištene opreme, strukture koda te korištene simulacije. Za generiranje referentnih brzina koristi se virtualni PLC (SoftController) ABB AC800 te programsko implementirani elektromotorni pogoni koji se sastoje od frekvencijskih pretvarača ABB ACS800 i asinkronih motora. Programski kod te simulacija implementirani su u okviru programskog paketa Control Builder. Referentne brzine pojedinih načina rada generirane su u simulaciji sa grafičkim sučeljem te u konačnici prikazane grafovima s detaljnim opisom rezultata mjerenja.

Abstract (english)

The master's thesis contains a detailed theoretical description of the cold rolling machine for the steel strip with a description of the functions of the management and the program part describing the equipment used, the code structure and the simulation used. To generate speed references are used the virtual PLC (SoftController) ABB AC800 and the program-implemented electromotive drives, which consists of the ABB ACS800 frequency inverters and asynchronous motors. Program code and simulation are implemented within the Control Builder program package. The speed references of individual modes are generated in a simulation with a graphical interface and ultimately shown in graphs with a detailed description of the measurement results.
