1. A method for controlling a wind turbine, the method comprising:
predicting at least one of a deflection of a wind turbine tower, tower vibrations, a nacelle yaw, or tower clearance control of one or more wind turbine components over a prediction horizon using a wind turbine model;
determining at least one behavioural constraint associated with operation of the wind turbine, wherein the at least one behavioural constraint is determined in dependence on at least one operational parameter of the wind turbine; and
using the at least one of the deflection of the wind turbine tower, the tower vibrations, the nacelle yaw, or the tower clearance control of the one or more wind turbine components in a cost function, and optimising the cost function subject to the at least one determined behavioural constraint to determine at least one control output for controlling operation of the wind turbine.
