基于单同步旋转坐标系下PI+谐振控制器的负序电流补偿

Conventional current control methods for grid-connected inverters often face challenges under unbalanced grid conditions and frequency variations. Although proportional–integral (PI) controllers in the synchronous reference ($dq$) frame perform well for positive-sequence regulation, they require dual $dq$ frames to handle negative-sequence components, increasing computational complexity. Proportio...
