    • Model based anticontrol of chaos 

      Morgül, Ömer (IEEE, 2003)
      We will consider model based anticontrol of chaotic systems. We consider both continuous and discrete time cases. We first assume that the systems to be controlled are linear and time invariant. Under controllability ...
    • On the control of chaotic systems in Lur'e form by using dither 

      Morgül, Ö. (Institute of Electrical and Electronics Engineers, 1999-10)
      In this paper we propose the application of dither for controlling chaotic systems in the Lur'e form. Dither is a high-frequency periodic signal and has the effect of modifying the nonlinearity for some nonlinear systems. ...
    • On the control of some chaotic systems by using dither 

      Morgül, Ö. (Elsevier, 1999)
      In this Letter, we propose the application of dither for controlling chaotic systems in Lur'e form. Dither is a high frequency periodic signal that can be used for stabilization of limit cycles in some type of nonlinear ...
    • Plane-wave dynamics of single crystal upconversion optical parametric oscillators 

      Akgün, Gülbin (Bilkent University, 1999)
      This thesis presents our investigation of the dynamics of single crystal up- conversion optical parametric oscillators (OPO’s). In these devices, parametric generation and sum frequency generation or second harmonic ...
    • An RC realization of Chua's circuit family 

      Morgül, Ö. (IEEE, 2000)
      In this brief, we consider a Wien bridge-based resistance–capacitance ( ) chaotic oscillator. We show that this circuit realizes the well-known Chua’s oscillator under some conditions. We also show that this circuit is ...
    • A switching synchronization scheme for a class of chaotic systems 

      Morgül, Ö.; Akgül, M. (Elsevier, 2002)
      In this Letter, we propose an observer-based synchronization scheme for a class of chaotic systems. This class of systems are given by piecewise-linear dynamics. By using some properties of such systems, we give a procedure ...
    • Wien bridge based RC chaos generator 

      Morgül, Ö. (IET, 1995)
      A new circuit, which is formed by coupling a Chua diode with a Wien bridge oscillator in parallel, is presented. This circuit contains only resistors, capacitors and operational amplifiers. By choosing element values ...
