Commande robuste du système d’énergies renouvelables

Abstract

This project focuses on the development of advanced control strategies for a wind energy conversion system based on a Doubly-Fed Induction Machine, aiming to improve efficiency, stability, and robustness. Three control methods were studied : • Direct Vector Control (DVC) offers fast response but is sensitive to flux estimation errors. • Indirect Vector Control (IVC) more stable but depends on accurate machine parameters. • Fuzzy Logic Control combines flexibility and high robustness, well-suited to rapid wind speed variations. Simulation results using MATLAB/Simulink show that fuzzy control delivers the best dynamic performance and robustness compared to classical vector control approaches.
