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 ratedwindspeed.
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。

Any wind turbines need power control. We aim at capturing wind energy in below-ratedwindspeed as much as possible and limiting the aerodynamic power in above-ratedwindspeed.
MW variable speed constant frequency wind turbine from shenyang university of technology is a variable pitch wind turbine, it can change pitch to adjust power above ratedwindspeed.
