直驱型永磁同步风电系统的模糊控制器的研究

摘要

文章以桨距各部分的数学模型为基础，以功率偏差为控制输入，以实际经验为依据确定了模糊论域和模糊规则库，以额定风速以上系统输出恒功率为目标，设计了直驱型永磁同步风电系统的 PID 控制器。利用 Mat-lab 建立了直驱型永磁同步风力发电控制系统的仿真模型，并进行了仿真，仿真结果表明模糊 PID 控制器能够进行变桨距控制，风能转换系统可以实现恒功率输出。%In this paper,the mathematical model of each part of the pitch is taken as the basis,and the control power deviation is adopted as the input. The fuzzy domain and fuzzy rules are determined by practical experience. Taking constant power output of the above rated wind speed as the object,a PID controller has been designed for direct drive permanent magnet synchronous wind power system. Matlab is utilized to establish the simulation model of direct drive permanent magnet synchronous wind type of generator control system. Simulation results show that the fuzzy PID con-troller is able to achieve variable pitch control,and the constant power output can be realized by the wind energy con-version system.
