Abstract : This paper discusses the application of the Passivity-Fuzzy Logic Controller (PFLC) approach to the control of a dual-feed induction generator (DFIG) for wind energy conversion. This approach effectively addresses model uncertainty by relying on the correlation between passivity and type-2 fuzzy logic control. The paper includes a comprehensive comparison with passive-based control (PBC). The proposed techniques are tested under varying parameters to assess their performance. Simulation results indicate that PFLC surpasses PBC in rise time and reference tracking while also reducing current harmonic distortion (THD) to 6.61%. Combining passivity and type-2 fuzzy control enhances dynamic performance, reduces the system's sensitivity to disturbances, and increases its resilience to parameter changes.
