Determining Blade Pitch Angle Sensitivity for PID Controller

A blade pitch angle sensitivity of wind turbine can be used to design a PID pitch controller. However, it is not simple to get a blade pitch angle sensitivity of wind turbine , becuase it depends on not only a blade-pitch angle but also wind speed. This paper suggests the analytical method of determining a blade pitch angle sensitivity. Finally, examples have been simulated to evaluate the proposed method in this paper.
