Stabilization of Discrete Time Systems By Reflection Coefficients
(Krasovskii Inst Mathematics & Mechanics Ural Branch Russian Acad Sciences, 2017)
For single-input single-output discrete-time systems, we consider a stabilization problem by a fixed order controller. A number of examples show that such controller may not exist. It is assumed that the controller depends ...
The circle as an attractor of an iterated function system on the plane
(Academic Press Inc Elsevier Science, 2007)
We give an iterated function system (IFS) on the plane with the circle as attractor. In doing this, we also give a sufficient condition for radially contracting functions on the plane (or on R-n) to be a contraction. A ...
The common vector approach and its comparison with other subspace methods in case of sufficient data
(Academic Press LTD- Elsevier Science LTD, 2007)
This paper presents an application of the common vector approach (CVA), an approach mainly used for speech recognition problems when the number of data items exceeds the dimension of the feature vectors. The calculation ...
A note on a theorem of Rantzer
(John Wiley & Sons LTD, 2002)
In this note we fill the missing cases of a theorem of Rantzer on the relationship between n-convex directions and the growth condition. We mainly show that if a second or a third order polynomial is a 3-convex direction, ...
Derivatives of the restrictions of harmonic functions on the Sierpinski gasket to segments
(Academic Press Inc Elsevier Science, 2007)
We give an explicit derivative computation for the restriction of a harmonic function on SG to segments at specific points of the segments: The derivative is zero at points dividing the segment in ratio 1:3. This shows ...
Stabilisation of discrete-time systems via Schur stability region
(Taylor & Francis LTD, 2018)
In this paper, we consider the stabilisation problem of discrete-time systems by affine compensator. Using the known properties of the Schur stability region of monic polynomials, we give conditions under which stabilising ...
On the Robust Stability of Polynomial Matrix Families
(Int Linear Algebra Soc, 2015)
In this study, the problem of robust asymptotic stability of n x n, polynomial matrix family, in both continuous-time and discrete-time cases, is considered. It is shown that in the continuous case the problem can be reduced ...
On One Application of Convex Optimization to Stability of Linear Systems
(Krasovskii Inst Mathematics & Mechanics Ural Branch Russian Acad Sciences, 2015)
One of the most important problem of control theory is control of switched systems. This problem is related to the common quadratic Lyapunov function problem and one of the way to solve it is LMI (Linear Matrix Inequalities) ...
Random search of stable member in a matrix polytope
(Elsevier Science BV, 2016)
Given a matrix polytope we consider the existence problem of a stable member in it. We suggest an algorithm in which part of uncertainty parameters is chosen randomly. Applications to affine families and 3 x 3 interval ...
On Stability of Parametrized Families of Polynomials and Matrices
(Hindawi Publishing Corporation, 2010)
The Schur and Hurwitz stability problems for a parametric polynomial family as well as the Schur stability problem for a compact set of real matrix family are considered. It is established that the Schur stability of a ...
