摘要
在额定风速以上的风况下以变速变桨风力机为研究对象,提出了模糊自抗扰独立变桨控制方案,以减轻干扰的影响。针对系统各状态量分别设计自抗扰控制器,利用模糊逻辑控制对自抗扰控制器参数进行整定。利用Matlab软件对提出的控制策略与PD控制、自抗扰控制进行仿真对比。结果表明:所提出的控制策略能更有效地对模型的非线性和风速等不可知量进行观测及处理,达到抑制风力机不平衡载荷、保证发电质量的控制目标。
Taking the variable speed variable pitch wind turbine as an object of study,which works under the condition above rated wind speeds,a fuzzy logic individual pitch control scheme was proposed based on auto disturbance rejection controller（ADRC）to reduce the influence of disturbance.For each of the state variables in the system,an auto disturbance rejection controller was designed,of which the parameters were adjusted by fuzzy logic control.The control strategy proposed was then compared with that of the PD and ADRC on the Matlab.Results show that the newly proposed control strategy can be used to observe and deal with the nonlinearity,wind speed and other unknown quantities to restrain the blade offset and achieve the goal of constant power output.
