We present a collective blade pitch control algorithm for floating offshore wind turbines. Control objectives are to regulate the rated power of a generator and to maintain the stability of platforms in region 3. To achieve these, the optimal control method with integral action is basically used with a Kalman filter. The Kalman filter is designed to estimate the wind speed as well as wind turbine and platform states. The performances of the designed controllers are tested and verified by comparing the standard deviations of the assigned parameters of our controllers with those of the standard controllers, according to the IEC standard conditions.
