Fractional Second Order Sliding Mode Controller for The Control of Wind Generator Based on a DFIG

Abstract

In order to reduce the chattering phenomena in the conventional sliding mode controller, which appears mostly in the rotor currents of doubly fed indication generator (DFIG), a new Fractional Second Order Sliding Mode Controller is proposed. In this controller, the sliding surfaces are chosen so that they will be compatible with the errors in the rotor currents. The simulation results, show the robustness of the proposed control model, the minimization of the chattering and they improve the total harmonics distortion of the rotor currents
