Abstract :
We derive a model for a wind turbine tower in the plane of the turbine blades, that comprises a non-uniform SCOLE system and a two-mass drive-train model (with gearbox). The input of this model is the electric torque created by the electrical generator. We show the impedance passivity and well-posedness of this model in the natural state space. We also prove that generically, this system can be strongly stabilized by feedback using information about the angular velocity of the nacelle and the angular velocity of the generator rotor.
