摘要

本文确定了光伏系统中光伏电池、DC/DC变换器和并网DC/AC逆变器的设计准则，并建立了Simulink模型。采用模糊逻辑和PI控制来保证DC/DC变换器和DC/AC逆变器的控制。比较了模糊逻辑和PI控制的结果。仿真结果表明，模糊控制比PI控制更有效，逆变器输出电流呈正弦波，服从同相角线电压波形。

Designing of a fuzzy controller for grid connected photovoltaic system's converter and comparing with PI controller

The design criteria of PV cell, DC/DC converter and grid connected DC/AC inverter which belong to the photovoltaic system are determined and Simulink models are established in this study. The control of DC/DC converter and DC/AC inverter is ensured by using fuzzy logic and PI control. The results of fuzzy logic and PI control were compared. It was seen in the result of simulation that fuzzy logic control is more efficient than PI control, output current of inverter has sinusoidal waveform and it follows the waveform of line voltage with same phase angle.
