چکیده
In this paper, Direct Torque Control (DTC) approaches of induction motor (IM) drives has been proposed and it is extensively implemented in industrial variable speed applications. This paper presents a unique direct torque control (DTC) approach for induction motor (IM) drives fed by using a fuzzy logic controller. The intention is to develop a low-ripple high-performance induction motor (IM) drive. The presented scheme is founded on the emulation of the operation of the conservative six switch three-phase inverter. It routines the dc current to re-construct the stator currents desired to estimate the motor flux and the electromagnetic torque. This methodology has been adopted in the design of the vector selection table of the suggested DTC approach through fuzzy logic controller. The modelling and simulation results of direct torque control of induction motor have been confirmed by means of the software package MATLAB/Simulink.
