To the grid connected wind turbine, the purpose of controlling it working at optimal tip speed ratio or about is to capture maximum wind energy.

对并网型风力机，控制其在额定风速下运行在最佳叶尖速比或其附近，主要是希望它能捕获到最大的风能。

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.

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。

Make use of adjustable fan unit system, touching switchgear adjust voltage, keep the wind speed of working area always in perfect status.

采用可调风量风机系统，轻触式开关调节电压，保证工作区风速始终处于理想状态。
