摘要

虽然全阶观测器已经成功地应用于大型风力涡轮机的状态空间桨距控制，但显然，还没有记录使用降阶观测器。利用600kW水平轴风力发电机的模型，我们证明了使用降阶观测器来获得风速估计用于干扰调节控制可以抑制柔性模式并减少大型风力发电机的结构疲劳。

Use of reduced-order observers for feedback control in large wind turbines may reduce fatigue damage from excitement of flexible modes

While full-order observers have been successfully applied in state-space blade-pitch control of large wind turbines, the use of reduced-order observers has, apparently, not been documented. Using a model of a 600kW horizontal-axis wind turbine, we demonstrate that the use of a reduced-order observer to obtain wind speed estimates for disturbance accommodation control may dampen flexible modes and lead to reduced structural fatigue in large wind turbines.
