Direct Torque Control of Induction Motors

This document presents Direct Torque Control (DTC) implementation for induction motors. The control system includes Simulink simulation block diagrams for modeling the complete DTC system, M-files for calculating flux sectors using sector determination algorithms, and M-files for generating appropriate switching signals based on torque and flux hysteresis controllers. These components form the essential framework for implementing direct torque control in induction motors. The Simulink simulation enables comprehensive analysis and validation of the control algorithm's dynamic performance and stability characteristics. Accurate flux sector calculation is critical for proper motor parameter estimation and precise control realization, typically implemented through coordinate transformation and angle computation algorithms. The switching signal generation module implements the core control strategy by selecting optimal voltage vectors from the inverter switching table based on torque and flux error states. Therefore, these simulation models and code files play a vital role in developing and optimizing direct torque control systems for induction motors.
