Generalized Data–Driven Predictive Control: Merging Subspace and Hankel Predictors

open access: yesMathematics, 2023
Data–driven predictive control (DPC) is becoming an attractive alternative to model predictive control as it requires less system knowledge for implementation and reliable data is increasingly available in smart engineering systems.

Analytical solutions to some generalized and polynomial eigenvalue problems

open access: yesSpecial Matrices, 2021
It is well-known that the finite difference discretization of the Laplacian eigenvalue problem −Δu = λu leads to a matrix eigenvalue problem (EVP) Ax =λx where the matrix A is Toeplitz-plus-Hankel.

Stable factorization for Hankel and Hankel‐like matrices [PDF]

open access: yesNumerical Linear Algebra with Applications, 2001
AbstractThis paper gives fast O(n2) algorithms for the factorization of positive‐definite and indefinite Hankel matrices. The algorithms are based on the concept of displacement structure and are valid for the more general class of Hankel‐like matrices. The positive‐definite algorithm is proven to be backward stable.

On the spectral properties of real antitridiagonal Hankel matrices

open access: yesSpecial Matrices, 2022
In this article, we express the eigenvalues of real antitridiagonal Hankel matrices as the zeros of given rational functions. We still derive eigenvectors for these structured matrices at the expense of prescribed eigenvalues.

On some identities and Hankel matrices norms involving new defined generalized modified pell numbers

open access: yesJournal of New Results in Science, 2021
The aim of this paper is to introduce a generalization of Modified Pell numbers. Some identities about this new sequence are obtained and also investigated some relationships with another sequence.

Unitary automorphisms of the space of Toeplitz-plus-Hankel matrices

open access: yesSpecial Matrices, 2015
Our motivation was a paper of 1991 indicating three special unitary matrices that map Hermitian Toeplitz matrices by similarity into real Toeplitz-plus-Hankel matrices.

Catalan Transform of k-Balancing Sequences

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2021
In this work, the Catalan transformation (CT) of k-balancing sequences, Bk,nn≥0, is introduced. Furthermore, the obtained Catalan transformation CBk,nn≥0 was shown as the product of lower triangular matrices called Catalan matrices and the matrix of k ...

Companion matrices and their relations to Toeplitz and Hankel matrices

open access: yesSpecial Matrices, 2015
In this paper we describe some properties of companion matrices and demonstrate some special patterns that arisewhen a Toeplitz or a Hankel matrix is multiplied by a related companion matrix.We present a necessary and sufficient condition, generalizing ...
