Transient response of digitally controlled DC-DC converter using only feedforward control
Reo Sumita, Terukazu Sato (Oita Univ.) EE2020-4
Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed a control method of a switching power supply using only feed-forward control, which is reflected in the duty ratio, by calculating the influence of these disturbances on the output voltage by detecting the load current and input voltage. Since only feed-forward control is used, there is no closed loop and there is no possibility of oscillation, and there is no degradation of stability due to changes in phase margin and gain margin when connected to capacitive and inductive loads. This paper compares the transient characteristics of the feed-forward control scheme with that of the PID control, which is a feedback control.
