Research on Flux Weakening Control for the Rotor Flux Oriented Control of an Induction Motor

The paper presents a revised flux weakening control method which is based on traditional method to improve the transient performance of a rotor flux oriented induction motor system.The torque current tracking error is handled on the calculation of the reference flux current in field weakening region.The system simulation model is first constructed using Matlab/Simulink,and then the proposed method is implemented in digital ac spindle driver.Simulative and experiment results all confirm the validity of the proposed method.
