Performance Comparison of FOC and DTC Techniques for SynRM in EV Applications

Synchronous Reluctance Motors (SynRM) are becoming popular in electric vehicles, renewable energy, and domestic applications over PMSM and Induction machines due to their advantages, such as the absence of rare earth materials, less copper losses, robust construction, and high efficiency. The performance of a SynRM is enhanced by its rotor geometry through improving the saliency ratio, along with its control strategies. This work focuses on the performance evaluation of control strategies, comparing two distinct methods applied to Synchronous Reluctance motors: Field oriented control (FOC) and Direct torque control (DTC), targeting EV applications. These control techniques are prominent strategies for SynRM, offering precise control over speed and torque. The features of both methods are illustrated and simulated for various EV torque and speed testing profiles using MATLAB/Simulink software.
