摘要
介绍一种用来控制变桨距大型风力发电机组的模糊控制器。具体介绍了模糊控制算法设计、基本模糊查询表的建立。给出了采用模糊控制的风力发电机控制系统模型结构图。仿真结果表明 ,不论是跟随性能还是抗干扰性能 ,采用模糊控制比用PID控制效果好 ,能克服被控系统模型参数变化和非线性等不确定因素 ,鲁棒性强 ,稳态精度高。
A fuzzy controller to be used to control varying oar distance large scaled wind power generator is introduced. The algorithm design of fuzzy control and establishment of basic fuzzy interrogation table are presented concretely.The model structural diagram of the wind power generator controlled by fuzzy control is given.The result of simulation shows that not only the following up performance but also the anti-interference capability,using fuzzy control gets better results than using PID control.The uncertainty variation of model parameters of controlled system and non-linearization are overcome. In addition,the robustness and the stability are higher.
