Abstract
Wind power generation, as a crucial component of renewable energy, plays a pivotal role in global energy transition. Pitch control is one of the core technologies that enhance the efficiency and stability of wind turbine systems, being essential for achieving efficient wind power system operation. In response to the issues of slow response speed and low control accuracy present in existing pitch control algorithms, this study proposes a novel adaptive fuzzy PID-based pitch control algorithm. By integrating a fuzzy logic controller with a traditional PID controller, this algorithm achieves rapid response and precise tracking of wind speed variations. The research employs the MATLAB/Simulink platform for simulation modeling, comparing the performance differences between the new algorithm and traditional PID algorithms under various operating conditions. Results indicate that the proposed adaptive fuzzy PID algorithm improves dynamic response speed by approximately 30% and reduces steady-state error by about 25%. Additionally, the algorithm exhibits strong robustness and disturbance rejection capability, maintaining effective control performance in complex and variable wind farm environments. The findings of this study provide new insights and technical support for optimizing pitch control in wind power systems, significantly contributing to enhancing the power generation efficiency and stability of wind turbines.
