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. .
