According to the controlling requirement of megawatt wind driven generator with variable propellerpitch of horizon axis, the hydraulic controlsystem of a variable propellerpitch is designed.
针对兆瓦级水平轴变桨距风力发电机的控制要求,设计了变桨距液压控制系统。

The system operates by a lever (28) which controls a pitchcontrol unit (10) which in turn controls engine speed and also the pitch of propeller blades (12) of propeller (14).
The controllable pitchpropellercontrolsystem based on fuzzy and neural network control is proposed, the result shows that the system design is feasible and effective.
