Abstract :
The proposed current control scheme is based on predictive control with an identification algorithm added to compensate for the inaccuracy of the motor parameters. The parameters of armature inductance and flux linkage are identified by comparing the difference of current between a calculation model and an actual motor. The improvements in dynamics and accuracy of the current controller have been verified
