Robust Power Control of Three-Phase Grid-Connected Inverter
This paper proposes using Linear Matrix Inequality (LMI) for robust controller design in a three-phase grid-connected inverter (GCI). The controller, applied to a three-phase dc-ac inverter, integrates state feedback and error correction within the dq-rotational frame to eliminate offset errors. An LMI-based optimization minimizes settling time despite uncertainties in the L-filter (expressed as resistance and…
