Abstract

In this paper, a rotor flux observer in the stator current vector orientation synchronous reference frame (DQ reference frame) is introduced and analyzed first. Then indirect vector control is combined with the DQ rotor flux observer, and a slip frequency correction method is proposed to achieve flux and torque decoupling control. Basic principles and system schematic diagram are described. Simulations and experiments results verify the proposed correction method.
