The modelling of a single-phase inverter is first introduced; then a first-order repetitive control is developed for the proposed grid-connected inverter. Moreover, a high-order repetitive controller is adopted to further improve the robustness against the uncertainties in the period of signals.
In this line, there are many control methods developed for grid-connected inverter, such as PI control, hysteresis control, deadbeat control, robust control, repetitive control, and adaptive control [20 – 26].
To solve the problem, in this article, we present a feedforward repetitive control (FRC) scheme for grid-tied inverters in microgrids to track the fundamental reference signal and suppress the harmonic signals simultaneously.
This paper proposes a frequency-adaptive dual-mode repetitive control (FA-DMRC) strategy for grid-tied inverters to address harmonic compensation degradation in conventional DMRC caused by non-integer delays during grid frequency variations.
