Abstract

U radu je predstavljen algoritam automatske identifikacije parametara sinkronog motora s trajnim magnetima. Algoritam je strukturno podijeljen na dva nezavisna dijela. Prvi dio temelji se na rekurzivnoj metodi najmanjih kvadrata, a procjenjuje četiri najvažnija električna parametra stroja. Drugi dio temelji se na opserveru stanja minimalnog reda za identifikaciju vektora proširene elektromotorne sile, iz čije faze se PLL estimatorom računa brzina vrtnje motora. Algoritam je detaljno matematički opisan, a onda i simulacijski provjeren u Matlab/Simulnk programskom okruženju.

Abstract (english)

Online parameter identification algorithm was proposed. Algorithm is structurally divided into two independent parts. First one is based on recursive least square (RLS) algorithm for computing four of the machine's most important electrical parameters. Second part consists of the minimal state observer for computing extended electromotive force vector, whose phase is used by the Phase-Locked-Loop (PLL) estimator for computing rotor speed of the machine. Algorithm is mathematically described in detail and verified by simulations in Matlab/Simulink environment.
