Comparative analysis of the chosen field-weakening methods for the Direct Rotor Flux Oriented Control drive system

In this paper, an analysis of the induction motor control scheme based on the Direct Rotor Flux Oriented Control (DRFOC) for a whole speed range, including field- weakening (FW) regions is presented. Two field-weakening algorithms have been com- pared and verified through simulation with a 3.0 (kW) induction motor drive.
