Abstract

U ovom radu teoretski su opisani principi rada i struktura suvremenih elektromotornih
pogona, koji su najčešće temeljeni na asinkronim motorima i frekvencijskim pretvaračima.
Nadalje, predstavljen je dinamički model asinkronog stroja te su opisani principi
transformacije koordinatnih sustava statora i rotora zbog toga jer vektorski sustav upravljanja
zahtjeva uvođenje zajedničkog koordinatnog sustava pričvršćenog za rotor.
U završnom dijelu rada projektiran je regulacijski krug struje i brzine vrtnje uz primjenu
kriterija optimuma dvostrukog odnosa, a rezultati simulacija prikazani su grafovima.

Abstract (english)

This thesis theoretically discuss the operating principles and structure of modern electric
motor drives which are mostly based on induction motors and frequency converters.
Furthermore, a dynamic model of an induction machine is presented, and the principles of
transformation of stator and rotor coordinate systems are described since the field oriented
control system requires the introduction of a common coordinate system attached to the rotor.
In the final section, a control circuit of the current and speed of rotation was designed using
the criterion of the damping optimum, and the results of the simulations are presented
graphicaly.
