摘　　要：本文在分析各种算法优缺点基础上，针对风力机及太阳能电池阵列数学模型表达式复杂和应用不便的特点，基于二次插值法缩小最大功率工作点的出发点，改进常见的最大功率跟踪控制方法一功率扰动观察法，结合两种算法的优点提出了一种改进算法去跟踪最大输出功率。并在MATLAB环境下搭建功率扰动观察法最大功率跟踪控制模型，运用S-函数模块编写改进算法模型，仿真结果对比分析，改进算法在搜索时间及精度上都有所提高。In this paper, based on analyzing the advantages and disadvantages of all kinds of algorithms.Wind turbine and solar arrays mathematical model expression is complicated and the application is inconvenient, moreover both the quadratic interpolation and power perturbation and observation method have their own limitations,so that with the new method which took advantages ofaU algorithms to track the maximum power output,the simulation models have been established in MALTLAB. Improved algorithm using S - write function modules model to compare and analyze the simulation results.This new method in search time and accuracy are improved.
