| Abstract: | In this paper, the significance of the digital control for UPS is summarized. Several digital control schemes for UPS inverter- digital PID control, Deadbeat control and repetitive control- are introduced, and the principles and control laws of deadbeat control and repetitive control are deduced in detail. Several schemes are introduced to tackle the problem of robustness and control delay of deadbeat control. Finally sliding-mode control and fussy control are introduced, and the development trend of digital control technology is pointed out. |
