In this paper, the current controller synthesis and real-time testing in a grid-tied inverter system is discussed. The current loops are implemented using an observer–based linear quadratic regulator. The disturbance observer is employed to ensure zero steady state error in the presence of model uncertainties. A simulation model implemented in SimscapeTM ElectricalTM is used to evaluate the control algorithm in real–time on a Speedgoat real–time system with an IO334 field–programmable gate array (FPGA) I/O module. The results show the effectiveness of the proposed solution.
