Research on field-weakening control of induction motor based on torque current component of the voltage closed-loop

The paper is based on vector control research on field-weakening control strategy of induction motor. In field-weakening induction motor torque output declines, in order to improve dynamic performance, on the basis of the existing voltage closed-loop field-weakening control strategy, the torque current tracking error is handled on the calculation of the reference excitation current in field-weakening region, so as to improve the tracking ability of current and torque of the motor output properties. Use MATLAB/SIMULINK simulation model of induction motor field-weakening control system. System simulation and experimental results will be proved the feasibility and effectiveness of the method.
