Abstract
A wind turbine having a rotor, which has at least one rotor blade adjustable about its longitudinal axis via a pitch control, and a generator, driven by the rotor, having a speed regulator, which takes a control difference in the rotational speed and generates a control variable for the pitch control, and a generator regulator, which takes a power conductance and determines a rotational speed setpoint and a power setpoint, wherein a pilot control is provided that uses an inverse controlled system to determine a control variable for the pitch control, the inverse controlled system determining a power torque (MP) from the rotational speed setpoint and the power setpoint and also an acceleration torque (MB) from the change in the rotational speed setpoint over time and outputting the control variable for the pitch control as an output variable that provides pilot control for the output variable from the speed regulator.
