Nonlinear voltage control for three-phase dc-ac converters in hybrid systems: An application of the pi-pbc method 

Serra, Federico M.; Fernández, Lucas M.; Montoya, Oscar D.; Gil-González, Walter; Hernández, Jesus C. (2020-05-20)
In this paper, a proportional-integral passivity-based controller (PI-PBC) is proposed to regulate the amplitude and frequency of the three-phase output voltage in a direct-current alternating-current (DC-AC) converter ...
