    • Decentralized blocking zeros and the decentralized strong stabilization problem 

      Ünyelioğlu, K. A.; Özgüler, A. B.; Özgüner, Ü. (IEEE, 1995)
      This paper is concerned with a new system theoretic concept, decentralized blocking zeros, and its applications in the design of decentralized controllers for linear time-invariant finite-dimensional systems. The concept ...
    • Decentralized control and periodic feedback 

      Khargonekar P. P.; Özgüler, A. B. (IEEE, 1994)
      The decentralized stabilization problem for linear, discretetime, periodically time-varying plants using periodic controllers is considered. The main tool used is the technique of lifting a periodic system to a time-invariant ...
    • Decentralized strong stabilization problem 

      Özgüler, A. Bülent; Ünyelioğlu, Konur A. (IEEE, 1992-06)
      In the decentralized strong stabilization problem for linear time-invariant finite-dimensional systems, the objective is to stabilize a given plant using a stable decentralized controller. A solvability condition for this ...
    • Fixed zeros of decentralized control systems 

      ÜÜnyelioglu, K. A.; Özgüner, Ü.; Özgüler, A. B. (IEEE, 2000)
      This paper considers the notion of decentralized fixed zeros for linear, time-invariant, finite-dimensional systems. For an N-channel plant that is free of unstable decentralized fixed modes, an unstable decentralized fixed ...
    • Improving AWE accuracy using multipoint Pade approximation 

      Çelik, Mustafa; Ocali, Ogan; Tan, Mehmet Ali; Atalar, Abdullah (IEEE, 1994-05-06)
      A new method is proposed for dominant pole-zero analysis of large linear circuits containing both lumped and distributed elements. This method is based on a multipoint Pade approximation. It finds a reduced order s-domain ...
    • Interframe differential vector coding of line spectrum frequencies 

      Erzin, Engin; Çetin, A. Enis (IEEE, 1993-04)
      Line Spectrum Frequencies (LSF's) uniquely represent the Linear Predictive Coding (LPC) filter of a speech frame. In many vocoders LSF's are used to encode the LPC parameters. In this paper, an interframe differential ...
    • On algebraic properties of general proper decentralized systems 

      Yu, R.; Sezer, M. E.; Gao, W. (Elsevier, 1993)
      The new concepts of the decentralized output feedback variable polynomial, the decentralized output feedback cycle index of general proper systems, and the geometric multiplicities of decentralized fixed modes are introduced. ...
    • Pole-zero computation in microwave circuits using multipoint Padé approximation 

      Celik, M.; Ocali, O.; Tan, M. A.; Atalar, Abdullah (Institute of Electrical and Electronics Engineers, 1995-01)
      A new method is proposed for dominant pole- zero (or pole-residue) analysis of large linear microwave circuits containing both lumped and distributed elements. The method is based on a multipoint Padé approximation. It ...
    • Stabilization and disturbance rejection for the wave equation 

      Morgül, Ö. (Institute of Electrical and Electronics Engineers, 1998-01)
      We consider a system described by the one-dimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize the system, we propose a dynamic boundary controller applied at the free end ...
