For large offshore wind turbines (WTs), pitch control is usually used for regulating generated power to the rated value and for mitigating the dynamic loads that at the wind speeds above the rated speeds. However, tracking the pitch angle accurately and quickly can hardly be realized due to complex operating environments, uncertain system parameters, various disturbances, and coupled effect between wind, wave, and turbine structure. In this paper, an individual pitch control system based on a neural adaptive strategy is proposed to address the problems related to uncertain system parameters and various disturbances. The proposed control method can achieve zero error tracking for the pitch angle in a predefined finite time. The design and stability analysis for the proposed method is elaborated. A simulation model is established in Matlab/Simulink, and by comparing it with the traditional PID control method, the merit of the proposed control scheme is verified.
