Sliding Mode Control In A Wind Turbine System

This paper is interested in the control of a DFIG by a sliding mode controller, used in a wind system. The conversion chain comprises a three-blade turbine, the DFIG, a rotor-side converter, a capacitor, grid-side converter and a line-side filter. The sliding mode control is used to control the direct and quadratic current of the rotor; this type of regulator was used especially for its robustness against the parametric variations of the generator.
