摘要：
In this paper, a backstepping nonlinear control scheme has been designed for a single-phase grid-connected inverter system with local load. The main objective of the proposed controller is to simultaneously improve the quality of the local load voltage while injecting clean current to the grid with unity power factor. Furthermore, this control approach ensures the seamless transfer between grid-connected and stand-alone operation modes without adjusting the controller structure. The proposed controller is validated by a Lyapunov stability analysis as well as via instantaneous dynamic circuit simulation in PLECS software.
