摘要: 以Matlab/Simulink为仿真平台,建立了光伏电池通用仿真模型,分析了传统最大功率跟踪算法中的扰动观察法和电导增量法原理、优缺点和各自应用的场合,根据光伏阵列的非线性输出特性提出了基于扰动观察法的模糊控制策略。仿真表明,当外界环境发生变化时,新的控制算法能够更快地跟踪最大功率点并具有良好的稳态性能。

Abstract: Based on the simulation platform of matlab/simulink, a generic simulation model of photovoltaic(PV) battery is built. The principles, pros and cons as well as the applications of two traditional methods on maximum power point tracking (MPPT) control strategy, i.e., perturb & observe method and inc-cond method are analyzed. In addition, a fuzzy control strategy based on the perturb & observe method is proposed according to the nonlinear output characteristics of PV arrays. The simulation results show that the fuzzy control strategy can fast track the maximum power point with good static performance when the ambience changes.

Key words: PV model, maximum power point tracking (MPPT), fuzzy control, Matlab
