Advanced Direct Torque Control of Induction Motor
S. Suresh, B. Karthik
Abstract
Torque ripples during Operation of an Induction Motor may be dampened with the use of a model of the motor's Direct Torque Control. In order to ascertain the efficiency of a motor drive system, traditional methods use a number of different regulating tactics. Since direct torque control (DTC) is simple to implement and provides for excellent transient and steady-state performance when combined with a PI controller and a rotation of coordinates, it has been chosen as the control technique. The suggested model is meant to fix the issue of modulation at high-speed Induction motor. Using the multilevel inverter model as a starting point, the suggested DTC of the induction motor will introduce the control variables and the switching table of the hysteresis controller. PWM's gated pulse is used as part of a switching method. Results from experiments demonstrate improved suppression of torque and flux ripples. Because of this, the Induction motor may be run with the precision of a clock. When activated, the closed-loop flux regulation technique ensures optimal performance in terms of rated speed, torque, and stator flux. The suggested model was validated using MATLAB/Simulink to improve upon previous techniques of analysis
