چکیده
This paper presents a robust control design methodology for three-phase AC-DC converters operating under industrial resistive loads, addressing key challenges such as parameter uncertainties, load variations, and external disturbances. The proposed approach is based on an advanced control strategy, offering superior stability margins, enhanced disturbance rejection, and improved robustness compared to conventional control methods. The study incorporates detailed system modeling to capture the dynamics of the converter under real-world conditions. A comprehensive sensitivity analysis is conducted to identify critical parameters affecting system performance, ensuring the robustness of the control design against uncertainties. The mathematical framework for the controller is thoroughly derived, providing a clear pathway for implementation in industrial settings. Simulation results illustrate the effectiveness of the proposed method, demonstrating improved transient and steady-state performance over traditional control techniques such as PID and linear quadratic regulators (LQR). Specifically, the controller achieves faster response times, reduced overshoot, and better load regulation under varying operating conditions. This work not only highlights the theoretical advancements in robust control but also emphasizes its practical applicability in demanding industrial environments. The findings suggest that the adoption of control can significantly enhance the reliability and efficiency of AC-DC converters, making it a promising solution for modern industrial power systems.کلیدواژه ها
