Claim 0:
1. A controller for a wind turbine having an aerodynamic rotor with at least one rotor blade, the controller comprising:
circuitry forming a cascade control arrangement and having an outer control loop and an inner control loop, wherein the controller is configured to control a rotation speed of the aerodynamic rotor of the wind turbine,
wherein the inner control loop is configured to receive one or more input signals indicative of one or more characteristics chosen from a change in the rotation speed, an acceleration of the rotation speed, a function of a change in the rotation speed and a function of an acceleration of the rotation speed,
wherein the one or more input signals received by the inner control loop comprises a rotor acceleration power or a rotor acceleration torque.
