Three-Phase Induction Motor Direct Torque Control Simulation

I have developed and successfully debugged a simulation program for direct torque control (DTC) of three-phase induction motors. This implementation employs advanced control techniques including flux and torque hysteresis comparators, switching table-based voltage vector selection, and motor parameter estimation algorithms to achieve superior motor control efficiency. The simulation comprehensively models motor dynamics, drive circuits, and control system interactions. Throughout the development process, I conducted thorough research on various aspects of motor control, including power electronics drive systems, DTC algorithm optimization, and motor characteristic analysis. The program incorporates key MATLAB/Simulink components such as Clarke/Park transformations, flux observers, and pulse-width modulation (PWM) generation blocks. I also consulted with domain experts to validate the implementation and ensure correct system operation. This simulation provides valuable insights into motor control principles and demonstrates how advanced control techniques can enhance motor efficiency and dynamic performance. The code structure includes modular subsystems for control logic, inverter modeling, and motor equations, making it easily adaptable for different motor specifications. I am pleased to share this program and believe it will contribute significantly to research and practical applications in motor control engineering.
