| Abstract: | This paper aims at the difference of motor parameter variation when vector control system lies in the two different zone,torque invariable zone and power invariable zone.It puts forward the structure of the MRAC Vector Control System with the mechanical characteristic curve fuzzy zonal control.This system implements auto zonal control by fuzzy control,and auto revising motor parameter variation by MARC.It effectively solves the magnetic field positioning problem under motor parameter variation in Vector Control System.The theoretical analysis and the experiments demonstrate the validity of this project. |
