A reduced infinite-order repetitive control (RIORC) is introduced in this paper, and the feasibility of this method is verified by applying it to a single PWM grid-connected inverter. The experimental results show that the RIORC can be used in practice with finite space and finite. . A novel fractional-order repetitive control based on phase angle information interpolation is proposed for single-phase LCL-type inverters in this paper. Conventional fractional-order repetitive control typically relies on inaccurate grid frequency information detected by a phase-locked loop or the. . Abstract: Single-phase uninterruptible power supply (UPS) is widely used in all kinds of important electrical equipment to ensure the smooth implementation of power supply. The core part of the UPS is the inverter circuit, and the control of the output voltage of the inverter circuit is of great. . High order repetitive control (HORC) has been reported to improve the robustness of the control system that incorporate the non-periodic disturbance. In fact, the higher the order is, the more memory cells are needed, and the more total delay time of the control system is needed. Notably, in. .
