Damping analysis of floating offshore wind turbines (FOWTs): a new control strategy reducing the platform vibrations

Wind Energy Science, 2022
Abstract. In this paper, the coupled dynamics of the floating platform and the wind turbine rotor are analyzed. In particular, the damping is explicitly derived from the coupled equations of the rotor and floating platform. The analysis of the damping leads to the study of instability phenomena, thus obtaining the explicit conditions that lead to the ...
