Abstract	This paper presents a new approach for the control of wind turbines. The proposed strategy can be decomposed in two part. In a first stage control strategy, we provide a nonlinear dynamic feedforward strategy for rotor speed regulation along with a nonlinear dynamic feedback to be robust to model uncertainties. It guarantees convergence of the rotor speed to its desired value. This first part only looks at the rotor dynamics and the aerodynamics. The tower dynamics is not taken into account. In a second stage control strategy, we provide a control action that minimize the tower fatigue. The strategy is largely validated for the onshore case. The proposed control approach can be extended to the offshore case and a first validation is proposed.
