Basing on analyzing the wind turbine mathematic model, the principle and structure of the variable pitch, a 3-phased PMSM electric servo pitch-controlled system was proposed based on the single neuron PID (SNPID) algorithm, and then considering the simplicity and regulable weights of SNPID algorithm, a servo pitch controller boasting of three closed loops including SNPID position, speed and torque was designed. Simulation results prove the proposed method feasible and useful with the help of Matlab/simulink.%在分析风力发电机数学模型、变桨控制原理以及变桨伺服系统硬件结构的基础上,提出了基于单神经元PID(SNPID)算法的三相永磁同步电动机变桨伺服控制系统.利用单神经元PID算法原理简单、权值可调的特点,设计了单神经元PID位置、速度及转矩三闭环结构的变桨伺服控制器.通过Matlab/simulink工具箱仿真结果证明了控制方案的有效性和可行性.
