Design of Robust Power Control of a Three-phase Grid-Connected Inverter
This thesis describes a method of Linear Matrix Inequality (LMI) to determine robust gain for a three-phase grid-connected inverter (GCI). The robust controller technique is applied to a three-phase dc-ac inverter. This controller employs state feedback and integration of the tracking error in the 𝑑𝑞 rotational frame so that the offset-error can be eliminated. An…
