Abstract

In inertial load drive applications, such as railway traction system and electric vehicles, a feed-forward current control mode is applied, which employs a single pulse mode of inverters in a wide speed range. Tuning both the primary and secondary motor parameters is essential for sophisticated torque control in the feed-forward current control mode. In this study, an auto tuning method focusing on both the primary and secondary motor parameters is developed for more precise torque control in the feed-forward current control region. The proposed method is characterized by the primary angular frequency dependency of the PI compensator voltage. The proposed method is verified via simulation and a small-scale model experiment with a 0.75 kW induction motor with an inertial load.
