|a Sažetak na hrvatskom: Asinkroni strojevi su najčešće korišteni strojevi u elektromotornim pogonima. Elektromotorni pogoni s asinkronim strojem mogu biti vektorski ili skalarno upravljani. U ovom radu obrađuje se vektorsko upravljanje asinkronim strojem bez mjernog člana brzine vrtnje. Vektorsko upravljanje temelji se na upravljanju referentnim vektorom napona prilikom čega se koristi modulacija širine impulsa.
Upravljanje asinkronim strojem izvršava se korištenjem Texas instruments platforme koja se sastoji od upravljačke ploče i upravljačke kartice. Algoritam upravljanja preuzet je iz Texas instruments biblioteke i učitan u programski paket Code Composer Studio. Korištenjem navedene platforme i programskog paketa, napravljeni su pokusi zaleta, reverziranja i kočenja. Na dobivenim odzivima postoje oscilacije koje su u skladu s očekivanjima zbog neprecizne estimacije toka i brzine.

|a Sažetak na engleskom: Induction machines are commonly used in variable-frequency drives. Electrical drives with induction machines can be scalar or vector controlled. This paper is based on sensorless vector control (field-oriented control) of 3-phase induction machine. Vector control is based on the management of the reference voltage vector.
Field-oriented control of induction machines is accomplished using Texas Instruments platform that consists of the control kit and control card. The control algorithm is uploaded from Texas Instruments library and loaded into the software package Code Composer Studio. By using the mentioned platform and software package, the experiments of acceleration, reversing and breaking of the induction machines were conducted. The responses received have oscillations that are in line with expectations due to inaccurate estimation of flow and speed.
