Auto Tuning Method to identify motor stator and rotor parameter in Field-Orientation-Controlled Induction Motor

In inertial load drive applications such as railway traction system and electric vehicles, there exists feed-forward current control including single pulse mode in a wide speed rage. In this study, the auto tuning method focusing on both the primary and secondary sides of the motor is proposed for more precise torque control in the feed-forward current control region. The proposed method is featured by the primary angular frequency dependency of the PI compensator voltage. The proposed method is verified by small-scale model experiment.
