Fuzzy-PCI Control Method for Three-phase Grid-connected Inverter
摘要
Abstract
To improve the control effect of grid-connected inverter,a fuzzy-proportional-complex-integral(PCI)control method is proposed to eliminate AC disturbance self-adaptively. As the steady-state error of the control method could be zero when the disturbing signal is at a specific frequency,it has a better control effect than proportional-integral control. Moreover,LCL filter is chosen,and its feedback capacitance current is used as inner-loop to form the active damping control method,which can restrain LCL resonance effectively and reduce the ultraharmonics in grid-connected current obviously. The simulation and experimental results illustrate the validity and advantage of the proposed method.关键词
