In this paper, the authors present a direct flux and torque control of three phase induction motor drive using PI and fuzzy logic controller. The DTC is one of the most excellent direct control strategies of stator flux and torque ripple of IMD. The conventional method of DTC, it uses PI for speed regulator where speed reduced under transient and dynamic state. This drawback was reduced by the proposed system the speed is regulated by PI and torque is controlled by fuzzy logic controller. The control system is based on DTC operating principles.
