Abstract

U radu je opisan postupak puštanja u pogon sustava vektorskog upravljanja brzinom vrtnje SMPM-a bez mjernog člana brzine vrtnje pomoću pokusa zaleta, reverziranja i zaustavljanja stroja.
Upravljanje sinkronim motorom s trajnim magnetima ostvareno je korištenjem Texas Instruments pretvaračke platforme koja se sastoji od upravljačke energetske ploče i kontrolne pločice na kojem je smješten programirljivi mikrokontroler. Pomoću programskog okruženja Code Composer Studio učitan je gotov algoritam upravljanja preuzet iz Texas instruments biblioteke. Zbog nemogućnosti estimacije brzine i pozicije rotora prilikom izvođenja sekvenci zaleta, reverziranja i zaustavljanja motora pri brzinama bliskim 0 o/min modificiran je upravljački kôd tako da se pri brzinama manjim od 750 o/min sustavom upravlja u otvorenoj petlji. To omogućava nesmetano zaustavljanje rotora jer se pozicija rotora ne estimira već izravno diktira generatorom rampe.

Abstract (english)

The thesis describes a drive commissioning based on vector control of Sensorless permanent magnet synchronous motor (PMSM) with tests of running up, reversing and stopping the motor.
The management of PMSM is achieved by using a Texas Instruments converter platform that consists of the control kit and control card with a microprocessor. The control algorithm is loaded from the Texas Instruments library with programming environment Code Composer Studio. Due to the estimation impossibility of rotor position for speed close to 0 rpm the control code is modified which results in the open loop speed control for speeds less than 750 rpm. This allows smooth stopping of the rotor because the position of the rotor is not estimated but directly definited by the ramp generator.
