DFIG Wind Turbine Controlled by Sliding Mode and Fuzzy-Sliding Control Modes

Many non-linear controllers have been used to improve system performances and robustness of double fed induction machine (DFIG) based wind turbines like sliding mode control (SMC). However, this type controller is less efficient due a sign function that can lead chattering phenomenon. To overcome deficiency, the replaced by fuzzy logic (FLC). This what proposed in paper which deals with doubly generator turbine conversion (WECs) (FSMC). The applied back converters connect rotor windings grid, For side converter (RsC), we presented control, monitor active reactive powers independently, when grid (GsC) was set keep constant DC voltage desired power factor. effectiveness systems tested using Matlab/Simulink software under speed fluctuation parameters variation. simulation results showed FSMC more robust has better dynamic than SMC
