摘要：Two techniques for the control of a grid side converter in a wind energy conversion system. The system is composed of
a fixed pitch angle wind turbine followed by a permanent magnet synchronous generator and power electronic converters
AC-DC-AC. The main interest is in how to control the inverter in order to ensure the stability of the DC link voltage. Two
control methods based on the fuzzy approach are applied and compared. First, a direct Mamdani fuzzy logic controller is
presented. Then, a T–S fuzzy controller is elaborated based on a T–S fuzzy model. The Lyapunov theorem and H-infinity
performance are exploited for stability analysis. Besides, the feedback controller gains are determined using linear matrix
inequality tools. Simulation results are derived in order to prove the robustness of the proposed control algorithms and to
compare their performances.
