Five-Phase Induction Motor Modeling and Direct Torque Control (DTC) Implementation

In this work, we have developed a detailed model of a five-phase induction motor and implemented Direct Torque Control (DTC) techniques for motor regulation. The implementation begins with characterizing the motor's parameters and establishing a mathematical model to describe its dynamic behavior using state-space equations or d-q transformation models. The simulation phase involves coding the model in MATLAB/Simulink environment, where we implement key functions such as flux and torque calculators, hysteresis comparators, and switching table logic for DTC operation. The control algorithm continuously monitors stator flux and electromagnetic torque, generating optimal switching signals for the voltage source inverter to maintain precise torque control with rapid dynamic response. Through systematic simulation and validation, we demonstrate improved motor efficiency and performance characteristics, providing accurate modeling approaches and control methodologies for future motor control research and development.
