摘　　要：为提高逆变器并网的效率,降低并网电流的谐波畸变率,加快系统的动态响应速度,研究了基于电网电压定向的前馈解耦控制策略,设计了模糊PI控制器,制定模糊规则实现PI参数的整定,并在Matlab/Simulink中构建仿真模型以验证所提策略的有效性和可行性.In order to improve grid-connected invert-efficiency and reduce the grid current THD, and accelerate the dynamic response speed of the system, feed-forward decoupling method is studied and Fuzzy-PI is designed to draft the Fuzzy rule to adjust PI. The simulation is built to veri- fy the validity and feasibility of the control strategy in Matlab/Simulink.
