Abstract: A control system for stabilizing a floating wind turbine is provided. The control system includes a measuring device configured for measuring a wind field and a wave field, a determining device wherein the determining device is configured for determining an excitation frequency spectrum of the floating wind turbine on the basis of the measured wind field and/or the wave field and/or a current floater pitch angle of the floating wind turbine, and wherein the determining device is further configured for determining a balanced state of the floating wind turbine, wherein in the balanced state a natural frequency is outside of the excitation frequency spectrum and/or the current floater pitch angle is equal to a pre-defined floater pitch angle. The control system further includes an adjustment device which is configured for manipulating the current floater pitch and/or the natural frequency until the balanced state is met.
