Claim 8:
9. A controller for a wind turbine having at least one generator including a stator with a rotational axis about which a rotor is mounted, and the stator being electrically connected to an active rectifier actuated using an actuator, the controller comprising:
a position circuit configured to determine a mechanical position of the rotor with respect to the stator and output an electrical position signal,
a transformation circuit configured to predefine DC components of rotor fixed d and q coordinates for at least one three-phase stator current, and
a damping circuit configured to modulate and/or add at least one AC component to a q coordinate and/or modulate and/or add at least one DC component to a d component, wherein:
the AC component is determined based on the electrical position signal and/or the DC component is determined based on the electrical position signal, and
the damping circuit is connected to the transformation circuit,

at least one modulated q coordinate is generated which has the DC component and the AC component and is output to the actuator made available for the actuator, and/or at least one changed d coordinate is generated which has the DC component and the AC component and is output to the actuator.
