Robust Control10th IFAC Workshop on Time Delay Systems, TDS-2012 -- 22 June 2012 through 24 June 2012 -- Boston, MA -- 92592In this paper, a simple PI tuning method for time delay systems is proposed. The main characterization of the method is first to obtain the stability region in the (kp, ki)-plane using the stability boundary locus method and then to find the weighted geometrical center point of this region through its stability boundaries. Finally, this center point of the stability region in the (kp, ki)-plane gives the tuning parameters for the PI controller. The proposed method gives a simple and reliable result which is illustrated by several examples, and hence is practically useful for the designers in the analysis and control of time delay systems. © 2012 IFAC.eninfo:eu-repo/semantics/openAccessPI controllersPractical tuningStability boundary locusStability regionWeighted geometrical centerConference Object10PART 110210710.3182/20120622-3-US-4021.000272-s2.0-84866094325N/A
