Wind turbine hub load suppression method with independent variable pitch and yaw cooperative control
By using a method of independent pitch and yaw coordinated control, a nonlinear mechanism model was established and linearized. A two-degree-of-freedom control framework and state-space equation model were constructed. The model predictive controller was used to suppress the fatigue load on the wind turbine hub, which solved the performance degradation problem caused by the single control dimension in the existing technology and achieved a more efficient load suppression effect.
