Pseudo-Derivative-Feedback Control of Grid-Connected Inverters

This paper proposes a single-phase grid-connected inverter controlled by a pseudo-derivative-feedback (PDF) controller. The main circuit is based on a full-bridge inverter, focusing on the stability analysis and comparison of the transient responses of the PDF and proportional-resonant (PR) controllers. The control analysis examines the behavior of both controllers, discusses their performance, and validates their operation through simulations and experimental testing under two different conditions. Finally, the paper compares the controllers based on grid-connected simulation and experimental results.
