Abstract: This paper presents the Matlab/Simulink-based mathematical model of the rotor flux orientation vector control system of
an AC Asynchronous motor. The modules of the hysteresis current PWM controller and of the rotor flux linkage
observer are presented in detail. The simulation results are also given.
Key words: asynchronous motor; vector control; Matlab; simulation
