Abstract—In this paper, an optimal control scheme for single-phase grid-connected photovoltaic inverter is proposed. Besides a nonlinear mathematical model of the inverter in the DQ rotating coordinate is constructed. In addition, the designed controller has weaker dependence on the parameters of the system by selecting the appropriate performance control matrix. The simulation works show that this method can achieve zero steady-state error, has a good dynamic and static response, and it ensures that the system is robust in the case of parameters variations and fluctuations.
