Evaluating Robust Constant Switching Frequency Direct Torque Control for Doubly Fed Induction Motor
Year: 2025
Type: article
Abstract: This research presents an improved direct torque control (DTC) approach for a doubly-fed induction machine (DFIM) with two two-level voltage source inverters (VSI). One of the best control schemes to regulate the torque of the DFIM is the conventional direct torque control, or C-DTC. However, the low switching frequency of the DTC results in significant torque and flux ripples, which create acoustic noise that impairs the control performance, especially at low speeds. To address these limitations, the SVM-DTC technique is designed and simulated using MATLAB/Simulink to ensure full reference tracking, fast response, proper dynamic behavior, and low ripple level. The simulation results demonstrate how well the SVM-DTC control works for the DFIM in terms of speed, stability, and robustness.
