Abstract: This paper proposes a PIDTC and Type-2 fuzzy based DTC with asynchronous drive having three level diode clamped MLI using the SVPWM technique. However, PIDTC of asynchronous motor drive with three level diode clamped multilevel inverter produces a poor dynamic performance during staring, speed reversal and load perturbation conditions. Moreover PIDTC has considerable THD present in the current and also more distortion present in flux and torque. The above problems can be overcome by using type-2 fuzzy controllers instated of PI controllers with logical rules. The simulated results of F2DTC shows the better transient performance, less THD in current and poor distortion in torque and flux as differentiate to PIDTC.
