Analysis and design of switching and fuzzy systems
(Bilkent University, 2002-09)In this thesis we consider the controller design problems for switching and fuzzy systems. In switching systems, the system dynamics and/or control input take dierent forms in different parts of the underlying state space. ... -
Cat-state generation and stabilization for a nuclear spin through electric quadrupole interaction
(American Physical Society, 2017)Spin cat states are superpositions of two or more coherent spin states (CSSs) that are distinctly separated over the Bloch sphere. Additionally, the nuclei with angular momenta greater than 1/2 possess a quadrupolar charge ... -
Decentralized strong stabilization problem
(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 ... -
Dynamic output feedback stabilization of switched linear systems with delay via a trajectory based approach
(Elsevier, 2018)A new technique is proposed to construct observers and to achieve output feedback stabilization of a class of continuous-time switched linear systems with a time-varying delay in the output. The delay is a piecewise ... -
Encapsulation of vanillin/cyclodextrin inclusion complex in electrospun polyvinyl alcohol (PVA) nanowebs: prolonged shelf-life and high temperature stability of vanillin
(2012-08)We produced functional nanowebs, containing vanillin, having prolonged shelf-life and high temperature stability facilitated by cyclodextrin (CD) inclusion complexation. Polyvinyl alcohol (PVA) nanowebs incorporating ... -
An Evaluation of the Turkish stabilization and liberalization policies since 1980, in the light of Southern Cone experience
(Bilkent University, 1989)Purpose of this study is to compare the stabilization and liberalization policies implemented in the Southern Cone countries and Turkey. It investigates these policies in a comparative way, and evaluates the Turkish ... -
Finite time estimation through a continuous-discrete observer
(John Wiley and Sons, 2018)We study two broad classes of nonlinear time-varying continuous-time systems with outputs. For the first class, we build an observer in the case where a state dependent disturbance affects the linear approximation. When ... -
Fixed order controller design via parametric methods
(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 ... -
Further stability results for a generalization of delayed feedback control
(Springer, 2012-08-01)In this paper, we consider the stabilization of unstable periodic orbits for one-dimensional and discrete time chaotic systems. Various control schemes for this problem are available and we consider a recent generalization ... -
Global stabilization via local stabilizing actions
(Institute of Electrical and Electronics Engineers, 2006)Stabilization of a linear, time-invariant system via stabilization of its main diagonal subsytems is the underlying problem in all diagonal dominance techniques for decentralized control. In these techniques as well as all ... -
High energy dissipative raman soliton laser through XPM stabilization
(Optical Society of America (OSA), 2015-10)Dispersion, nonlinearity and gain determine the intracavity pulse behaviour. We show that pump depletion and XPM play a significant role in the stabilization of high energy dissipative Raman solitons. Using this theoretical ... -
Local convex directions
(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 ... -
Magnetic resonance electrical impedance tomography (MREIT) based on the solution of the convection equation using FEM with stabilization
(Institute of Physics Publishing, 2012-07-27)Most algorithms for magnetic resonance electrical impedance tomography (MREIT) concentrate on reconstructing the internal conductivity distribution of a conductive object from the Laplacian of only one component of the ... -
Monoid actions, their categorification and applications
(Bilkent University, 2017-01)We study actions of monoids and monoidal categories, and their relations with (co)homology theories. We start by discussing actions of monoids via bi-actions. We show that there is a well-defined functorial reverse action ... -
Multi-domain short peptide molecules for in situ synthesis and biofunctionalization of gold nanoparticles for integrin-targeted cell uptake
(American Chemical Society, 2015)We describe design and synthesis model of multidomain (modular) peptides (MDPs), which direct a reaction cascade coupling the synthesis and surface functionalization of gold nanoparticles (AuNPs) in a single step. The ... -
Neoliberal global remedies: From speculative-led growth to IMF-led crisis in Turkey
(2006)Turkey experienced a severe economic and political crisis in November 2000, and again in February 2001. The IMF has been involved with the macro management of the Turkish economy both prior to and after the crisis, and ... -
A new method for the computation of all stabilizing controllers of a given order
(Taylor & Francis, 2005)A new method is given for computing the set of all stabilizing controllers of a given order for linear, time invariant, scalar plants. The method is based on a generalized Hermite-Biehler theorem and the successive application ... -
A nonlinear control scheme for discrete time chaotic systems
(The International Federation of Automatic Control, 2012-06)In this paper we consider the stabilization problem of unstable periodic orbits of discrete time chaotic systems. We consider both one dimensional and higher dimensional cases. We propose a nonlinear feedback law and present ... -
Observer design and output feedback Stabilization of time varying systems
(Bilkent University, 2018-07)We study observer design and output feedback stabilization of switched and nonlinear time varying systems. To establish the stability of feedback switched systems with delay, we develop a new extension of a recently ... -
Observer-based control of a class of chaotic systems
(Elsevier, 2001)We consider the control of a class of chaotic systems, which covers the forced chaotic oscillators. We focus on two control problems. The first one is to change the dynamics of the system to a new one which exhibits a ...
