摘　　要：由于风的随机性与不确定性,对于风力发电机在高风速的情况下,控制系统的快速性与可靠性要求就更高。针对阵风的影响,该文设计了灰色预测对于阵风的影响提前预测,提高风机的可靠性。另外对于风机中偏差的变化情况,设计了模糊自调节PID系统,增强了控制的实时性。仿真结果表明灰色预测模糊自调节PID控制器与PID、模糊PID控制器相比较,实时性好,可以达到满意的结果。As a result of randominess and uncertainty of wind, pitch control system calls for the higher demand about the rapid respond and reliability in the high wind speed. Considering the effect of gust, the article designs gray prediction for forecasting the effects of gust to improve the reliability of wind turbines. Meanwhile, the design of fuzzy PID self-adjusting system enhances the real-time control. The simulation results show that self-regulating fuzzy gray prediction PID controller compared to PID, fuzzy PID controller, the former has better realtime and can achieve satisfactory results.
