On Anisotropy-Based Control Problem with Regional Pole Assignment for Descriptor Systems
P. 12-17.
Belov A. A., Andrianova O.
In this paper, anisotropy-based control problem with
regional pole assignment for descriptor systems is investigated.
The purpose is to find a state-feedback control law, which guar-
antees desirable disturbance attenuation level from stochastic
input with unknown covariance to controllable output of the
closed-loop system, and ensures, that all finite eigenvalues of
the closed-loop system belong to the given region inside the
unit disk. The proposed control design procedure is based on
solving convex optimization problem with strict constraints. The
numerical effectiveness is illustrated by numerical example.

A class of systems, described by algebraic-difference equations, is under consideration. Such systems are called descriptor (singular). For these systems the conditions of anisotropic norm boundedness are obtained. Anisotropic norm describes the root mean square gain of the system with respect to random Gaussian stationary disturbances, which are characterized by mean anisotropy. The conditions are ...

This paper deals with a state feedback H ∞ control problem for linear time-invariant discrete-time
descriptor systems with norm-bounded parametric uncertainties. To this end, bounded real lemma
(BRL) is extended on the class of uncertain descriptor systems. The control design procedure based
on the conditions of BRL for uncertain descriptor systems is proposed. Numerical examples are
included to illustrate ...

Linear stationary discrete-time descriptor systems with input sequences of random Gaussian nonzero-mean vectors with bounded mean anisotropy are under consideration. Conditions of anisotropic norm boundedness for such systems are given in terms of generalized discrete-time algebraic Riccati equations (GDARE) and linear matrix inequalities (LMI). On basis of these results, the algorithm of anisotropic norm computation ...

This paper is dedicated to optimal state-feedback
control problem for discrete-time descriptor systems in presence
of “colored” noise with known mean anisotropy level. Here
“colored” noise stands for a stationary Gaussian sequence,
generated by a linear shaping filter from the Gaussian white
noise sequence. The control goal is to find a state feedback
control law which makes the closed-loop system admissible ...

This paper deals with a state feedback H∞ control problem for linear discrete-time time-invariant (LDTI) uncertain descriptor systems. Considered systems contain norm-bounded parametric uncertainties in all matrices. Bounded real lemma (BRL) for descriptor systems with all known matrices is extended on the class of uncertain systems. The control design procedure based on the conditions of BRL for ...

The paper presents a novel concept of anisotropy-based analysis for linear discrete-time descriptor systems with nonzero-mean input signals. Descriptor systems are a general case of normal systems. They contain both differential (difference) equations and algebraic equations. In this paper, the algorithm for mean anisotropy computation of the Gaussian stationary random sequence with nonzero mean (we ...

The paper presents a solution of anisotropy-based suboptimal controller design problem for descriptor systems. The goal is to design a state feedback and full information control for the system such that the closed-loop system is admissible, and its anisotropic norm (mean anisotropy level is set) is bounded by a given positive real value.

inequalities. The obtained conditions are convex over ...
