Abstract
The present invention relates to control of wind turbines where a noise measure is taken into account. Control of a wind turbine is described where a control trajectory is calculated based on noise measure, the noise measure being determined from a predicted operational trajectory. In embodiments the predicted operational trajectories are calculated by using a model predictive control (MPC) routine.

- receiving a current operational state of the wind turbine;
- based on the current operational state, calculate one or more predicted operational trajectories, the one or more predicted operational trajectories include a predicted control trajectory, where a trajectory comprises a time series of at least one variable;
- determine at least one noise measure from at least one predicted operational trajectory;
- determine a control trajectory based on the at least one noise measure;
- and
- control the wind turbine based on the control trajectory.
