چکیده
This paper proposes design and simulation of Direct Torque Control of Induction Motor drive system is to minimize stator current distortion, electromagnetic torque and flux ripples. In this paper, Fuzzy Logic Controllers are proposed to replace the classical PI torque and flux controllers to achieve desired torque and flux with zero steady state error and also with good dynamic tracking and fast response. Fuzzy based torque and flux controllers are designed to optimize the stator voltages in d-q reference frame that applied to SVPWMDirect Torque Control. From the output of SVPWM-DTC based motor control signal is developed, hence the speed of IM is regulated. Simulation and the performance of the proposed FLC are analyzed. Simulation results showed that a significant improvement in dynamic torque and speed response in both steady and transient states and also a considerable reduction in Total Harmonic Distortion (% THD).

The direct torque control (DTC) speed control scheme of an induction motor surpasses the vector control in the sense that it controls the torque directly and does not use transformations and current modulator. In the traditional direct torque control (DTC) of induction motor, the low order harmonic component of stator current is very large when the motor is running at low speed. It leads to hig...

Direct torque control (DTC) of an induction motor fed by a voltage source inverter is a simple scheme that does not need long computation time and can be implanted without mechanical speed sensors and is insensitive to parameter variations. In principle, the motor terminal voltages and currents are sampled and used to estimate the motor flux and torque. Based on estimates of the flux position a...
