Simulink-Based Simulation Model for Direct Torque Control of Permanent Magnet Synchronous Motors (PMSM)

This Simulink-based simulation model implements Direct Torque Control (DTC) for Permanent Magnet Synchronous Motors (PMSM) using sensorless control techniques. As a pre-developed international model, it incorporates fundamental motor operating principles and sophisticated control strategies. The model simulates dynamic motor characteristics and control algorithms through mathematical implementations including Clarke/Park transformations, flux linkage calculations, and torque estimation algorithms using stator voltage and current measurements. It achieves high-precision motor control through optimized switching patterns and duty cycle calculations. The simulation considers practical application scenarios and environmental factors, incorporating robustness features like parameter adaptation and disturbance rejection mechanisms to ensure stability and performance across various operating conditions. This model serves as both an educational tool for researchers to study motor control theories and methodologies, and a reliable simulation platform for engineers to design and optimize PMSM control systems using MATLAB/Simulink's built-in blocks and custom S-functions for real-time implementation validation.
