Abstract: Abstract This paper examines the delay margin achievable by using PID controllers for linear time-invariant (LTI) systems subject to variable, unknown time delays. We derive explicit lower bounds on the delay margin of second-order unstable… read more here.

Abstract: A graphical control system design approach is proposed in this Letter considering time delay margin and time-integral performance criterion. For two free design parameters, time delay margin boundaries are plotted into 2D parameter plane by… read more here.

DOI: 10.1109/tac.2021.3059155
Abstract: In this article, we study delay robustness of PID controllers in stabilizing systems containing uncertain delays. We consider second-order systems and seek analytical characterization and exact computation of the PID delay margin, where by PID… read more here.
