    • Fixed order controller design via parametric methods 

      Saadaoui, Karim (Bilkent University, 2003)
      In this thesis, the problem of parameterizing stabilizing fixed-order controllers for linear time-invariant single-input single-output systems is studied. Using a generalization of the Hermite-Biehler theorem, a new ...
    • Local convex directions 

      Özgüler, Arif Bülent; Saadaoui, Karim (IEEE, 2001)
      A proof of a strengthened version of the phase growth condition for Hurwitz stable polynomials is given. Based on this result, a necessary and sufficient condition for a polynomial p(s) to be a local convex direction for ...
    • On stabilizing with PID controllers 

      Saadaoui, K.; Özgüler, A. Bülent (IEEE, 2007-06)
      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 ...
    • On the set of all stabilizing first-order controllers 

      Saadaoui, Karim; Özgüler, Arif Bülent (IEEE, 2003)
      A computational method is given for determining the set of all stabilizing proper first-order controllers for finite dimensional, linear, time invariant, scalar plants. The method is based on a generalized Hermite-Biehler theorem.
