In this paper, we propose an optimal voltage control for single-phase inverter with resonant LC filter via type-2 ILQ servo-control by 2nd-order polynomial. The improved ILQ control enables to follow the time-variant sinusoidal reference-voltage without phase delay. The excellent voltage control is achieved through the suppression of resonant output voltage.
