    • 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 ...
    • Boundary control of some infinite dimensional systems 

      Morgül, Ömer (IFAC, 2005)
      We will consider the feedback stabilization of a class of infinite dimensional systems by using boundary control, i.e. control inputs are applied at the boundaries of such systems. Such systems usually possess an internal ...
    • Low dimensional modelling and Dirichlét boundary controller design for Burgers equation 

      Efe, M. Ö.; Özbay, Hitay (Taylor & Francis, 2004)
      Modelling and boundary control for the Burgers equation is studied in this paper. Modelling has been done via processing of numerical observations through proper orthogonal decomposition (POD) with Galerkin projection. ...
    • On the boundary control of a flexible robot arm 

      Morgül, Ömer (IEEE, 2001)
      We consider a flexible robot arm modeled as a single flexible link clamped to a rigid body. We assume that the system performs only planar motion. For this system, we pose two control problems; namely, the orientation and ...
    • On the boundary control of Kirchhoff's nonlinear string 

      Morgül, Ömer; Shahruz, S. M. (IFAC, 2007)
      In this paper we propose two new classes of controllers which stabilize Kirchhoff's nonlinear string by using boundary control techniques. We assume that the boundary displacement is the only available measurement. The ...
    • On the control of two-link flexible robot arm with nonuniform cross section 

      Dogan, M.; Morgül, Ö. (SAGE, 2010)
      We consider the motion of a two-link flexible arm with nonuniform cross section. We obtain the equations of motion by using the extended Hamiltons principle. These equations consist of coupled partial differential equations ...
    • On the stabilization of a flexible beam with a tip mass 

      Conrad, F.; Morgül, Ö. (Society for Industrial and Applied Mathematics, 1998-11)
      We study the stability of a flexible beam that is clamped at one end and free at the other; a mass is also attached to the free end of the beam. To stabilize this system we apply a boundary control force at the free end ...
    • On the stabilization of the wave equation 

      Morgül, Ömer (Springer, 1993)
    • PDE control of a rotating shear beam with boundary feedback 

      Doğan, M.; Morgül, Ömer (IEEE, 2009-08)
      We consider a flexible structure modeled as a shear beam which is clamped to a rigid body at one end and is free at the other end. The whole structure is free to rotate on the horizontal plane. We first model the system ...
    • Use of natural switching in the boundary control of DC/DC buck and boost converters 

      Koç, Yunus Emre (Bilkent University, 2021-08)
      DC-DC converters are extensively used in many power electronics applications such as photovoltaic systems, wind energy systems, DC motor drives, mobile devices, electric vehicles, etc. Fundamental performance criteria in ...
