Abstract	This work presents a systematic robust control synthesis procedure for regulating the rotation and attenuating vibrations on a wind turbine. The system time varying model is considered as a linear system subjected to polytopic uncertainties and Linear Matrix Inequalities conditions are presented for designing a statefeedback law. Simulation results compare the proposed approach performance to traditional strategies, such as Proportional-Integral control and Coleman Transform based state-feedback. Keywords— Wind Turbine, Robust Control, LMI, Polytopic Modeling Resumo— Este trabalho apresenta uma metodologia sistemática para śıntese robusta de controladores visando a regulagem da rotação e atenuação de vibrações em turbinas eólicas. O modelo variante no tempo do sistema é reescrito como um sistema linear sujeito a incertezas politópicas e condições na forma de desigualdades matriciais lineares são apresentadas para a śıntese de uma lei de realimentação de estados. Os resultados de simulação comparam o desempenho desta abordagem proposta em relação a estratégias tradicionais, como o controlador Proporcional-Integral e realimentação de estados baseada na Transformada de Coleman. Palavras-chave— Turbina Eólica, Controle Robusto, LMI, Modelagem Politópica
