Characterization of solutions of the discrete-time algebraic Riccati equation based on quadratic difference forms [PDF]

open access: yes, 2006
This paper is concerned with a characterization of all symmetric solutions to the discrete-time algebraic Riccati equation (DARE). Dissipation theory and quadratic difference forms from the behavioral approach play a central role in this paper. Along the

Pick matrix conditions for sign-definite solutions of the algebraic Riccati equation [PDF]

open access: yes, 2001
We study the existence of positive and negative semidefinite solutions of algebraic Riccati equations (ARE) corresponding to linear quadratic problems with an indefinite cost functional.

Asymptotic solutions of singularly perturbed linear differential-algebraic equations with periodic coefficients

open access: yesМатематичні Студії, 2023
The paper deals with the problem of constructing asymptotic solutions for singular perturbed linear differential-algebraic equations with periodic coefficients. The case of multiple roots of a characteristic equation is studied.

Algebraic entropy for algebraic maps [PDF]

open access: yes, 2015
We propose an extension of the concept of algebraic entropy, as introduced by Bellon and Viallet for rational maps, to algebraic maps (or correspondences) of a certain kind. The corresponding entropy is an index of the complexity of the map.

Analysis of servo-constraint problems for underactuated multibody systems [PDF]

open access: yesMechanical Sciences, 2013
Underactuated multibody systems have fewer control inputs than degrees of freedom. In trajectory tracking control of such systems an accurate and efficient feedforward control is often necessary.
