POSITION CONTROL OF A TWO-PHASE INDUCTION MOTOR WITH THREE PHASE INVERTER

Autor/autori: Ciprian AFANASOV, Mihai RATA

Rezumat: Scopul acestei lucrari este de a prezenta o structura de control a pozitiei pentru motoarele asincrone bifazate. In cazul acestei metode de reglare a pozitiei, motorul asincron bifazat este conectat ca o sarcina dezechilibrata intre cele trei brate ale invertorului. Strategia de comanda urmareste mentinerea permanenta a unui defazaj de 90° intre curentii din cele doua faze si reglarea vectoriala a pozitiei. Intregul sistem modelat simuleaza actionarea vectoriala a motorului asincron prin intermediul unui procesor DSP

Cuvinte cheie: control vectorial indirect, invertor trifazat, motor bifazat

Abstract: The aim of this paper is to present a position control structure for two-phase induction motors. A simple, but robust structure enables a position control of the driving system. The rotor flux field oriented control is realized by using indirect vector control based on the two-phase induction motor model. The control structure was implemented on a computer system, based on a fixed point digital signal processor (DSP). To verify the performances of the proposed driving system, are presented results obtained from simulation and practical determinations

Keywords: indirect vector control of induction machine, two-phase induction motor, three phase inverter
