摘　　要：风力发电在解决能源和环境问题上的积极意义,使其成为增长速度最快的绿色能源之一。偏航控制是大型风力发电机组的热门研究课题,偏航系统是典型的非线性、时变系统,常存在较大程度的参数变化和大时变负载与干扰。本文提出一种变论域模糊偏航控制策略,将变论域模糊控制与风向标反馈控制相结合,将风向数据与功率数据进行迅速的对比识别处理,来实现变论域模糊控制参数自整定和控制规则的自调整,提高偏航控制系统对风速扰动和参数变化的适应能力,最后进行风电机组偏航控制的仿真与实验,证明变论域模糊偏航控制具有动态响应快、抗干扰能力和鲁棒性强等优点。Positive significance of wind power on solving energy and environmental issues makes it to become the world＇ s fastest-growing new energy. Yaw control is a new research topic in study of wind turbines, and yaw control system is a typical nonlinear, time varying system, in which there are often a greater chance of parameter changes and large time-varying load and interference, so to establish a precise mathematical model is difficult. This paper presents a variable universe fuzzy yaw control strategy. The variable universe fuzzy control is combined with vane feedback control, and the wind data are quickly compared with power data recognition processing to realize the vari- able universe fuzzy control parameter self-tuning setting and control rules, so as to improve the yaw control system＇ s ability to adapt to wind disturbances and parameter changes. Finally, the experiments results show that variable universe fuzzy yaw control system has the advantages of fast dynamic response, strong anti-interference ability and robustness, etc.
