Fuzzy Second Order Sliding Mode Controller Based on Three-Level Fuzzy Space Vector Modulation of a DFIG for Wind Energy Conversion Systems

This paper presents a fuzzy second order sliding mode controller (FSOSMC) used for command stator active and stator reactive powers of doubly fed induction generator (DFIG). Based on the three-level space vector modulation with fuzzy logic (FL) controllers (FSVM). The powers command simulation results are obtained by using the proposed FSOSMC with FSVM and the traditional PI controller (Indirect Vector Command (IVC)) under different operating conditions. Also, sensitivity analyses simulation results for parameter variations are obtained to check the robustness of the system when using the proposed regulator. Finally, the simulation controlled system is illustrated for closed loop and simulation results are presented which show the validity and effectiveness of the proposed FSOSMC with FSVM inverter.
