Non
Discretizing LTI Descriptor (Regular) Differential Input Systems with Consistent Initial Conditions
A technique for discretizing efficiently the solution of a Linear descriptor (regular) differential input system with consistent initial conditions, and Time-Invariant coefficients (LTI) is introduced and fully discussed. Additionally, an upper bound for the error ‖x¯(kT)−x¯k‖ that derives from the procedure of discretization is also provided. Practically speaking, we are interested in such kind of systems, since they are inherent in many physical, economical and engineering phenomena
AN ANGLE METRIC THROUGH THE NOTION OF GRASSMANN REPRESENTATIVE
The present paper has two main goals. Firstly, to introduce different metric topologies on the pencils (F, G) associated with autonomous singular (or regular) linear differential or difference systems. Secondly, to establish a new angle metric which is described by decomposable multi-vectors called Grassmann representatives (or Plücker coordinates) of the corresponding subspaces. A unified framework is provided by connecting the new results to known ones, thus aiding in the deeper understanding of various structural aspects of matrix pencils in system theory
Transferring instantly the state of a linear singular descriptor differential system
In numerous computational applications in mechanics, in engineering, as
well as, in financial issues, the ability of manipulating instantly the
state vector from the input is more than significant. Thus, in this
paper, we extend a method for the instantly state transferring of linear
singular descriptor differential systems, which is based on impulsive
distributions. Using linear algebra techniques and the generalized
inverse theory, the input’s coefficients are determined
Symmetric/skew-symmetric homogeneous matrix descriptor (regular) differential systems with consistent initial conditions
This paper introduces the results of Thompson’s canonical form under
congruence for pairs of complex matrices with symmetric and skew
symmetric structural properties to the solution of higher order linear
matrix homogeneous differential systems. Under this approach, the main
equation is divided into five sub-systems whose solutions are derived.
Note that the regularity or singularity of matrix pencil predetermines
the number of sub-systems. The special properties of such systems may be
appeared in engineering and even in some financial models
Power series solutions for linear higher order rectangular differential matrix control systems
This paper is concerned with the solution of linear higher order
rectangular differential matrix systems which are appeared in many
applications of optimal and filtering control theory. The classical
power series method is employed to obtain the analytic solution of
linear higher order rectangular (singular) differential matrix
equations. In the present paper, the authors provide some preliminary
results for solving linear singular matrix systems with the power series
approach
Error Analysis of the Complex Kronecker Canonical Form
In some interesting applications in control and system theory, i.e. in
engineering, in ecology (Leslie population model), in
financial/actuarial (Leontief multi input - multi output) science,
linear descriptor (singular) differential/difference equations with
time-invariant coefficients and (non-) consistent initial conditions
have been extensively used. The solution properties of those systems are
based on the Kronecker canonical form, which is an important component
of the Matrix Pencil Theory. In this paper, we present some preliminary
results for the error analysis of the complex Kronecker canonical form
based on the Euclidean norm. Finally, under some weak assumptions an
interesting new necessary condition is also derived
Solution Properties of Linear Descriptor (Singular) Matrix Differential Systems of Higher Order with (Non-) Consistent Initial Conditions
In some interesting applications in control and system theory, linear descriptor (singular) matrix differential equations of higher order with time-invariant coefficients and (non-) consistent initial conditions have been used. In this paper, we provide a study for the solution properties of a more general class of the Apostol-Kolodner-type equations with consistent and nonconsistent initial conditions
