Comparison of PI controllers designed for the delay model of TCP/AQM networks
Ünal, Hakkı Ulaş; Melchor-Aguilar, Daniel; Ustebay, Deniz; Niculescu, Silviu-Iulian; Özbay Hitay (Elsevier Science BV, 2013)One of the major problems of communication networks is congestion. In order to address this problem in TCP/IP networks, Active Queue Management (AQM) scheme is recommended. AQM aims to minimize the congestion by regulating ... -
Further Remarks on Delay Dynamics in Oregonator Models
Ünal, Hakkı Ulaş; Boussaada, İslam; Niculescu, Silviu-Iulian (IEEE, 2016)Motivated by the fact that molecules reacting through some biological channels may need some time-lag due transcription and translation processes, this note is devoted to the study of stability properties of a delayed ... -
Further remarks on the effect of multiple spectral values on the dynamics of time-delay systems. Application to the control of a mechanical system
Boussaada, İslam; Tliba, Sami; Niculescu, Silviu-Iulian; Ünal, Hakkı Ulaş; Vyhlidal, Tomas (Elsevier Science Inc, 2018)A question of ongoing interest for linear Time-delay systems is to determine conditions on the equation parameters that guarantee the exponential stability of solutions. In recent works a new interesting property of ... -
Tracking sustained oscillations in delay model oregonators
Ünal, Hakkı Ulaş; Boussaada, İslam; Niculescu, Silviu-Iulian (Institute of Electrical and Electronics Engineers Inc., 2016)Sustained oscillations occur in many biological organisms and some chemical reactions. Belousov-Zhabotinskii (BZ) reaction is one these chemical oscillators, however, since its oscillatory behaviour is analogous to ones ...
