Delayed feedback control of PSJA for heat source cooling in a closed space

Abstract

This paper presents experimental results of DFC of heat source temperature using a plasma synthetic jet actuator（PSJA）. The unique feature of our study is that the control input to the PSJA is the duty ratio, a type of PWN, as the operating quantity. The feedback gain of DFC has not been established in previous studies, but in this study, the feedback gain of DFC was obtained by using LMI. In this study, the feedback gain of DFC derived by LMI was used to achieve efficient cooling of the heat source.
