Claim 3:
4. The method according to claim 1, comprising:
determining in successive discrete temporal steps, for each rotor blade of the at least three rotor blades, whether the actual blade angle of the rotor blade is an extreme angle, wherein the rotor blade angle is an extreme angle when:
the actual blade angle is larger than the actual blade angles of all other rotor blades of the at least three rotor blades, or
the actual blade angle is smaller than the actual blade angles of all other rotor blades of the at least three rotor blades; or

determining in successive discrete temporal steps, for each rotor blade of the at least three rotor blades whether the actual blade angle is a non-extreme angle, wherein the rotor blade angle is a non-extreme angle when:
the actual blade angle is smaller than an actual blade angle of at least one of the other rotor blades of the at least three rotor blades, and
the actual blade angle is larger than an actual blade angle of at least another one of the other rotor blades of the at least three rotor blades.
