    • Boundary control of a rotating shear beam with observer feedback 

      Dog̃an, M.; Morgül, O. (Sage Publications, 2012)
      We consider a flexible structure modeled as a shear beam which is free to rotate on the horizontal plane. We first model the system by using partial differential equations and we propose boundary feedback laws to achieve ...
    • Control and stabilization of a rotating flexible structure 

      Morgül, Ö. (Elsevier, 1994)
      We consider a flexible beam clamped to a rigid base at one end and free at the other end. We assume that the rigid base rotates with a constant angular velocity and that the motion of the flexible beam takes place on a ...
    • Dynamic boundary control of the timoshenko beam 

      Morgül, Ö. (Pergamon Press, 1992)
      We consider a clamped-free Timoshenko beam. To stabilize the beam vibrations, we propose a dynamic boundary control law applied at the free end of the beam. We prove that with the proposed control law, the beam vibrations ...
    • An exponential stability result for the wave equation 

      Morgül, Ö. (Elsevier, 2002)
      We consider a system described by the one-dimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize this system, we propose a dynamic boundary controller applied at the free ...
    • On the boundary control of beam equation 

      Morgül, Ö. (IFAC Secretariat, 2002)
      A flexible system described by Euler-Bernoulli beam equation is considered. The beam is clamped at one end, and is free at the other end. Boundary control force and torque inputs are applied at the free end of the beam. ...
    • On the strain feedback control of a flexible robot arm 

      Morgül, Ö. (American Automatic Control Council, 2011)
      We consider a flexible robot arm modeled as a rigid hub which rotates in an inertial space; a light flexible link is clamped to the rigid body at one end and is free at the other. We assume that the flexible link performs ...
    • An operator theoretic approach to robust control of infinite dimensional systems 

      Özbay, H. (Applied Mathematics Scientific Research Institute, 2013)
      The purpose of this paper is to give an overview of the skew Toeplitz approach to H∞ control of a class of infinite dimensional systems. Numerical steps involved in the computations of optimal and suboptimal controllers ...
    • Sensitivity reduction by strongly stabilizing controllers for MIMO distributed parameter systems 

      Wakaiki, M.; Yamamoto, Y.; Özbay, H. (Institute of Electrical and Electronics Engineers, 2011-12-09)
      This note investigates a sensitivity reduction problem by stable stabilizing controllers for a linear time-invariant multi-input multioutput distributed parameter system. The plant we consider has finitely many unstable ...
    • Stabilization and disturbance rejection for the beam equation 

      Morgül, Ö. (IEEE, 2001)
      We consider a system described by the Euler-Bernoulli beam equation. For stabilization, we propose a dynamic boundary controller applied at the free end of the system. The transfer function of the controller is a marginally ...
    • Stabilization and disturbance rejection for the beam equation 

      Morgül, Ö. (IEEE, Orlando, FL, USA, 2001)
      We consider a system described by the Euler-Bernoulli beam equation in a bounded domain with appropriate boundary conditions. To stabilize the system, we propose a dynamic boundary controller applied at the free end of the ...
    • 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 ...
    • Tangential Nevanlinna-Pick interpolation for strong stabilization of MIMO distributed parameter systems 

      Wakaiki, M.; Yamamoto, Y.; Ozbay H. (2012)
      We study the problem of finding stable controllers that stabilize a multi-input multi-output distributed parameter system while simultaneously reducing the sensitivity of the system. The plants we consider have finitely ...
