摘　　要：以单相光伏并网逆变器为研究对象,设计了一种基于准比例谐振控制的并网电流内环控制器和基于自抗扰控制的直流电压外环控制器的双闭环控制系统。基于Matlab/Simulink仿真平台和光伏并网系统的实验装置,对系统进行了仿真和实验研究,实验结果验证了该控制系统的合理性和正确性。Single-phase photovoltaic inverter was the study object. A grid dual-loop control system based on the quasi-resonant control ratio and net current inner loop controller and ADRC controlled DC voltage loop controller was designed. Finally, based on Matlab / Simulink simulation platform and photovoltaic systems experimental device, the system simulation and experimental studies were taken, and the reasonable and correct of the control system were verified by the simulation and experimental results.
