Abstract

Automatizirani procesi unaprjeđuju industrijsku proizvodnju. Važan dio elektromotornih pogona su sinkroni strojevi s trajnim magnetima. Najčešće se koriste za sustave u kojima je potrebna preciznost i pozicioniranje. U laboratorijskim uvjetima istraženo je vektorko upravljanje sikronim strojem s trajnim magnetima. Naglasak je stavljen na poboljšanje dinamičkih svojstava motora optimizacijom triju regulatora prisutnih u upravljačkoj petlji: regulator struje, brzine i pozicije. Optimizacija je provedena eksperimentalnim metodama. Zaključeno je kako se pažljivo odabranim parametrima regulatora mogu značajno unaprijediti svojstva upravljanog elektromotornog pogona. Bitno je napomenuti kako je za uspješnu optimizaciju upravljanja pogonom od iznimne važnosti znati točne parametre procesa i zahtjeve sustava prema kojima se treba prilagoditi upravljanje. Upravljanje pogonom izvedeno je direktno putem frekvencijskog pretvarača, ali i putem PLC-a te vizualizacijskog sučelja.

Abstract (english)

Automated processes improve industrial production. An important part of electric drives are synchronous machines with permanent magnets. They are mostly used for systems that require precision and positioning. In laboratory conditions was researched vector control for permanent magnet synchronous machine. Emphasis is placed on improving the dynamic characteristics of the machine optimizing three controllers present in the control loop: current control, velocity and position. Optimization is conducted by experimental methods. It was concluded that a carefully selected controller parameters can significantly improve the properties of controlled electric drive. It is important to note that for a successful optimization of drive control is highly important to know the exact parameters of the process and system requirements that have to be adapted by control. Drive control was performed directly by the frequency converter, or via PLC and graphic interface.
