ADRC control of an induction motor with varying parameters

Abstract

The vector control of an induction machine has a strong link to the motor parameter, resulting in a loss of robustness when the machine's parameters change during operation; This variation contributes significantly to the loss of dynamic performance in an unfavorable connection between the machine's flux and torque. The vector control system was used in this paper to implement active disturbance rejection control (ADRC). ADRC proposed that the system's robustness against motor parameter variations be improved, as well as the speed loop controller's performance be improved.
