Simulink Simulation Diagram for Direct Torque Control of Induction Motors

This document presents a Simulink simulation diagram for direct torque control of induction motors. The simulation model clearly illustrates the fundamental principles of direct torque control and its speed regulation capabilities. The control methodology typically employs a switching table algorithm based on flux and torque hysteresis comparators, where stator flux magnitude and electromagnetic torque are directly controlled through optimal voltage vector selection. Induction motors, being widely used in industrial and commercial applications, benefit from this technique's improved control precision and dynamic response. Through this simulation diagram, engineers can better understand the operational mechanism of direct torque control, particularly the implementation of flux observers and torque calculators using Simulink blocks like Clarke transformations and phase voltage measurements. The visual simulation enables deeper analysis of motor control strategies, facilitating practical implementation and optimization of drive systems.
