Boundary control of some infinite dimensional systems
(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 ... 
Computation of H∞ controllers for infinite dimensional plants using numerical linear algebra
(John Wiley & Sons, 20120214)The mixed sensitivity minimization problem is revisited for a class of singleinputsingleoutput unstable infinite dimensional plants with low order weights. It is shown that H∞ controllers can be computed from the ... 
Numerical computation and implementation of Hinfinity controllers for retarded and neutral time delay systems
(Bilkent University, 201712)Being the most commonly encountered systems in engineering applications, design of robustly stabilizing H∞ controller with maximum performance for timedelay linear timeinvariant systems has been an attractive topic in ... 
Numerical computation of H∞ optimal controllers for time delay systems using YALTA
(Elsevier B.V., 2016)Numerical computation of H∞ controllers for time delay systems has been a challenge since 1980s. Even though significant techniques are developed to obtain direct optimal controllers, application of these methods may require ... 
On stable controller design for robust stabilization of time delay systems
(IFAC, 2015)This paper studies the problem of robust stabilization of an infinite dimensional plant by a stable and possibly low order controller. The plant of interest is assumed to have only finitely many simple unstable zeros, ... 
On the boundary control of Kirchhoff's nonlinear string
(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 mixed sensitivity minimization for systems with infinitely many unstable modes
(Elsevier, 2004)In this note we consider a class of linear time invariant systems with infinitely many unstable modes. By using the parameterization of all stabilizing controllers and a data transformation, we show that ℋ ∞ controllers ... 
On the stabilization of a flexible beam with a tip mass
(Society for Industrial and Applied Mathematics, 199811)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 structure and implementation of the optimal QParameter in the oneblock Hinfinity control problem
(Bilkent University, 202012)In the robust control theory, H∞ methods are carried out to procure solutions to sensitivity minimization (nominal performance) and robust stability problems in general. These one – block control problems can be ... 
Sensitivity minimization by stable controllers: an interpolation approach for suboptimal solutions
(IEEE, 2007)Weighted sensitivity minimization is studied within the framework of strongly stabilizing (stable)H∞controller design for a class of infinite dimensional systems. This problem has been solved by Ganesh and Pearson, [8], ... 
Stable controllers for robust stabilization of systems with infinitely many unstable poles
(Elsevier, 2013)This paper studies the problem of robust stabilization by a stable controller for a linear timeinvariant singleinput singleoutput infinite dimensional system. We consider a class of plants having finitely many simple ...
