An Enhanced State Observer for DC-Link Voltage Control of Three- Phase AC/DC Converters

Publikation: Forskning - peer reviewTidsskriftartikel

Abstrakt

To regulate the DC-link voltage of three-phase AC/DC converters, an enhanced state observer (ESO)-based controller is presented in this letter. The proposed controller, contrary to the traditional ones, does not require the DClink current measurement and offers a “plug and play” capability, a rather high disturbance rejection ability and robustness against the DC-link capacitance parameter variation. The design procedure of the suggested controller is discussed, and its effectiveness is verified using experimental results.
