In this paper high-gain Proportional-Integral-Observer (PI-Observer) is used to estimate system states and wind disturbances. To guarantee the robustness and the desired performance, a disturbance rejection scheme is employed to compensate these disturbances. The proposed method realizes speed/power regulation during high wind regime. Control performance of the proposed scheme is evaluated against a baseline collective pitch controller (CPC). The results show that the proposed method can maintain fairly constant power/rotor speed without inducing extra load on the rotor.
