Direct torque control (DTC) of Induction Motor (IM) is primal requirement in traction and vehicle applications which has been employed for fast torque response in dynamic performance of IM drives. DTC decouple flux and torque control there for to achieve fast torque response, optimal inverter voltage selection is taken. In this paper, DTC method is employed for fast torque response utilizing PI-controller based on the voltage vector selection for inverter. Moreover, performance of IM is evaluated in term of torque response, speed response, stator current, rotor and stator flux in both time and d-q flux. Analysis reveals that PI-controller response fairly match the reference torque curve faster there for considered as best choice for DTC of IM.Refference:
