A simple, digital current control design for grid-connected inverters

In this paper, a robust predictive current control strategy has been proposed and studied. The predictive current control offers the potential for achieving more precise current control with minimum distortion and harmonic noise. However, the traditional predictive current controller has a poor performance under component parameter variations, and is less robust to filters inductance mismatch. Both simulation and experimental results show that the proposed method is more robust to parameter mismatch than traditional one
