A new discrete current vector regulator for torque controlled induction motor drives

The paper proposes a new current vector control strategy for torque controlled field oriented drives. The choice of the inverter switching vectors is based on the angular position of the rotor flux and on the reference and the motor current vectors in the switching vectors plane. The simulation results prove that the proposed method allows an improved DC bus utilization and lower motor phase currents THD to be obtained, compared to other current vector control techniques.
