摘　　要：本文首先介绍了小型风力发电系统的组成及最大功率跟踪原理,然后针对传统的定步长扰动观察法进行了改进,提出了一种基于模糊控制的变步长方法对风机系统进行最大功率跟踪。为了验证方法的可行性,在MATLAB/Simulink上搭建了风电系统的仿真模型进行仿真实验,最后仿真结果均证明了该方法能有效提高系统的搜索速度,减小系统波动。This paper introduces the composition of small wind power generation system and the principle of maximum power tracking at first. In order to improve the maximum power point tracking performance of the small-scale permanent magnet syn- chronous wind power system （WPS）, a variable step hill-climbing method suitable for the small-scale WPS based on fuzzy logic control is proposed, which is obviously superior to the traditional fix step hill-climbing. Based on it, the simulation system is built by using Matlab/Simulink. Finally, the results of simulation and experiment show that the method can effectively improve the search speed of the system and reduce the system fluctuation.
