神经网络模型参考控制在风力发电机组变桨距系统的应用

Application of Neural Network Model Reference Adaptive Control in Wind Turbines Variable Pitch System

变桨距系统是风力发电机组研究的关键部分。针对变速变距型风力发电机组的液压驱动式变距执行机构,提出了基于神经网络模型参考的PID变桨距控制方法,以解决变桨距机构的非线性、参数时变性、抗干扰和滞后性控制问题。

Variable pitch system is a key system of wind turbines. In order to solve non-linear, parameter time changing, anti-disturb and time-lag problems, a PID control method based on the neural network model reference adaptive control is presented and applied to the variabie speed adjustable pitch wind turbine control system, in which the variable pitch system is driven by hydraulic unit.
