提出了一种改进的桨距角控制方案——将系统频率偏差信号引入桨距角控制系统。
An improved pitch control scheme is presented by introducing a frequency deviation signal into the control system.
变桨距是通过改变风力机叶片桨距角来改变风力机的转速，从而调整发电机输出功率。
Pitch angle control system can change pitch, accordingly regulate the rotational speed and output power by adjusting blade incidence of wind-driven device.
在此基础上，利用非线性动态逆方法，设计了系统在额定风速以上工作时的桨距角控制律。
On the basis of this model, the nonlinear dynamic inversion method was applied to design the pitch Angle controller of the system working above the rated wind speed.
同时对悬停时桨叶的气弹稳定性有相当程度的影响，尤其是在高桨距角下这种影响是不能忽略的。
It is also seen that the transverse shear deformation and warping have effects on the aeroelastic stability of the rotor blade. These effects become larger at the higher thrust level.
