摘要
由于风切变效应及气动载荷的循环变化对风力机的影响,本文于重复控制的基础上设计了一种桨距角控制器。该种控制器由并联滤波器和重复控制器两部分组成,滤波器可减弱风速变化带来的扰动影响,重复控制器可使传动链具有较好的稳定性。实验结果显示,在外部风速变化扰动时,此控制器能有效保证风力机的功率稳定输出。同时,还对输入扰动和参数变化具有较好的动态能力。
Due to the wind shear effect and the cyclic change of pneumatic load for the wind turbine,this paper designs a pitch angle controller on the basis of repetitive control.This kind of controller is composed of parallel filter and repetitive controller,The filter can reduce the effects of disturbance for the changing of wind speed,repeatitive controller can make the transmission chain a good stability.Experiment result shows that when the external wind speed changing,this controller can effectively insure the stable output of the wind turbine.At the same time,it also has a good dynamic capability for inputting disturbance and parameter changing.
