    • A new PI and PID control design method for integrating systems with time delays: applications to AQM of TCP flows 

      Üstebay, Deniz; Özbay, Hitay; Gündeş, N. (World Scientific and Engineering Academy and Society (WSEAS), 2007-02)
      Allowable PI and PD controller gains for a class of unstable MIMO systems with input/output delays have been investigated in [5, 12]. Using the results of these studies, we propose a new method for tuning the parameters ...
    • On stabilizing with PID controllers 

      Saadaoui, K.; Özgüler, A.B. (2007)
      In this paper we give an algorithm that determines the set of all stabilizing proportional-integral-derivative (PID) controllers that places the poles of the closed loop system in a desired stability region S. The algorithm ...
    • PID controller design for fractional-order systems with time delays 

      Özbay, H.; Bonnet, C.; Fioravanti, A.R. (Elsevier, 2011-11-22)
      Classical proper PID controllers are designed for linear time invariant plants whose transfer functions are rational functions of sα, where 0<α<1, and s is the Laplace transform variable. Effect of inputoutput time ...
    • PID controller synthesis for a class of unstable MIMO plants with I/O delays 

      Gündeş, A.N.; Özbay H.; Özgüler, A.B. (2006)
      Conditions are presented for closed-loop stabilizability of linear time-invariant (LTI) multi-input, multi-output (MIMO) plants with I/O delays (time delays in the input and/or output channels) using PID (Proportional + ...
    • Reliable decentralised control of delayed MIMO plants 

      Gündeş, A. N.; Özbay, H. (Taylor & Francis, 2010-03)
      Reliable decentralised proportional-integral-derivative controller synthesis methods are presented for closed-loop stabilisation of linear time-invariant plants with two multi-input, multi-output (MIMO) channels subject ...
    • Resilient PI and PD controllers for a class of unstable MIMO plants with I/O delays 

      Özbay H.; Gündeş, A.N. (2006)
      Recently (Gündeş et al., 2006) obtained stabilizing PID controllers for a class of MIMO unstable plants with time delays in the input and output channels (I/O delays). Using this approach, for plants with one unstable pole, ...
    • Switching resilient PI controllers for active queue management of TCP flows 

      Üstebay, Deniz; Özbay, Hitay (IEEE, 2007)
      Active Queue Management (AQM) is used in computer networks to increase link utilization with less queueing delays. The fluid flow model or TCP based on delay differential equations supplies the mathematical background for ...
    • Tracking and regulation control of a 2-DOF robot arm with unbalance 

      Güler, Samet; Özgüler, A. Bülent (IEEE, 2012-08)
      Servomechanism synthesis for a two degree-of-freedom robot arm assembled on a vessel and affected from sea disturbances is considered. Dynamic equations of the robot arm with unbalance and of an approximate base disturbance ...
