摘　　要：为了克服传统爬山法在实现最大风能捕获中存在的振荡等问题,更合理地提高风能利用系数,提出一种基于模糊控制的爬山法。通过对风力机特性进行分析,在传统爬山法思想的基础上设计了模糊控制器,并给出了模糊控制规则,采用模糊逻辑控制的思想来实现最大风能捕获,提高风能利用率。根据风力机特性建立风力机模型,并对15 kW的风电机组分别进行了基于模糊控制的爬山法与传统爬山法的Matlab仿真,对比了两种方法在实现最大风能捕获时的差别。仿真结果表明,基于模糊控制的爬山法能够克服在实现最大风能捕获中存在的振荡等问题,使风能利用系数保持在最大值附近,满足最大风能捕获的要求,进而验证了该方法的可行性与正确性,具有一定的工程实际意义。In order to overcome traditional climbing method in achieving maximum wind energy tracking problem of shocks, better to improve wind energy utilization coefficient, this paper presents a climbing method based on fuzzy control. Through the analysis of wind turbine characteristics, designed the fuzzy controller on the basis of the ideas of the traditional climbing method, and presents a fuzzy control rules with fuzzy logic control to achieve the maximum wind energy capture, improve the utilization rate of wind power. Finally, wind turbine model was estab- lished aec3rding to its characteristics, and the 15 kW wind turbine were carried out based on the fuzzy control of climbing method and tradi- tional climbing method of Matlab simulation, compared the differences in the realization of maximum wind energy capture. Simulation results show that the climbing method based on fuzzy control can overcome some problems such as shock in the realization of maximum wind energy capture, wind energy utilization coefficient remained at near maximum value, to meet the requirement of maximum wind energy capture, and then verified the feasibility and correctness of the method that has certain practical significance.
