Abstract

A precise current regulation in order to achieve accurate torque control is an important part of higher-performance control systems in vector-controlled induction motor drives. Applying the conventional controllers in the reference frame oriented to the rotor flux requires relatively complex hardware to measure the direct and quadrature components of the stator currents. On the other hand, using a suitable controller to adjust the stator current in the stationary frame is complicated due to the changes in the operation frequency of induction motors. In this paper, a frequency domain method for designing current controllers is introduced and applied to a vector-control of an induction motor in the stationary reference frame. This controller regulates currents of the induction motor with zero near steady-state error and a good transient performance while it is not sensitive to induction motor parameters. The performance of the controller is investigated with and without back electromotive force compensation signals. The validity of the introduced controller is confirmed by simulation and experimental results.
