This paper introduces a variable structure robust controller for wind energy conversion systems based on brushless doubly fed reluctance machine. Two simultaneous control goals are tackled: maximization of the wind energy conversion efficiency and minimization of the machine copper losses. The proposed MIMO robust controller is systematically synthesized following a general design method for MIMO non linear affine systems. The design is approached through a theoretical framework based on the combination of variable structure techniques and the Lyapunov´s theory. Robustness to bounded disturbances and chattering minimization is attained.
