- State feedback controller Sine reference tracking Pole placement Grid-connected inverter Photovoltaic
- In this paper, the sine reference tracing state feedback current controller for the grid-connected inverter using the pole placement technique is proposed. The proposed state feedback controller can help to design the systematic current controller by using the pole arrangement technique according to given system requirements on the AC grid voltage conditions. Therefore, the state feedback control algorithm that can track the sign input voltage is designed using the average model of the inverter, and the proposed method are verified from experimental results of the 200W scale-down two-stage photovoltaic power conversion system.
