Abstract	Predictive current control (PCC) methods have been widely implemented for grid-connected voltage source inverters (VSIs) recently to achieve better output performance, however, facing the challenge of high sensitivity to uncertain system disturbances and inevitable time delay. In this paper, a new PCC scheme has been proposed for a single-phase VSI to improve the quality of the current fed to the grid as well as enhance the system stability and robustness. The proposed control scheme is developed from the traditional predictive current controller along with a simple weighted filter predictor (WFP) and a robust adaptive voltage compensator (AVC). The results of simulation and experiment investigation have demonstrated the improvements of the proposed control scheme in inverter output quality and robustness to parameter variations.
