1. A method of controlling a wind turbine having a tower and a rotor at which a plurality of rotor blades are mounted, the method comprising:
determining, in real time, at least one damping characteristic of at least one vibration mode related to the wind turbine; and
controlling the wind turbine based on the damping characteristic,
wherein determining the damping characteristic comprises determining a damping level calculated to depend on a relative change of a vibration magnitude related quantity with time;
wherein a time course of the damping level never falls below a damping threshold where undamped vibrations occur.
