The present disclosure relates to a method (100) for controlling a wind turbine (10) having a plurality of actuators (364). The method (100) comprises receiving operational data (366) of the wind turbine (10) and determining an operational state of the wind turbine (10). The method (100) comprises using a control model (370) to predict potential operational states depending on operation of the actuators (364) over a finite period of time. The control model (370) comprises an aeroelastic model (371) to determine loads (375) based on operational data (366). The control model (370) further comprises a strength calculation module (372) to calculate secondary load parameters (374) from the loads (375), constraints being defined for the secondary load parameters. The method (100) comprises optimizing a cost function over an optimization period of time, subject to the constraints, to determine an optimum trajectory comprising commands for the actuators (364). Finally, the method (100) comprises using the first commands of the optimum trajectory to control the actuators (364). The disclosure also relates to a controller (360) for a wind turbine (10) configured to implement such method (100).
