A study on Vandermonde-like polynomial matrices
Augusto Ferrante, Fabrizio Padula, Lorenzo Ntogramatzidis
A new class of structured matrices is presented and a closed form formula for their determinant is established. This formula has strong connections with the one for Vandermonde mat…
New geometric results in eigenstructure assignment
Fabrizio Padula, Augusto Ferrante, Lorenzo Ntogramatzidis
The focus of this paper is the connection between two foundational areas of LTI systems theory: geometric control and eigenstructure assignment. In particular, we study the propert…
Fixed poles of the disturbance decoupling problem by dynamic output feedback for biproper systems
Fabrizio Padula, Lorenzo Ntogramatzidis
This paper investigates the disturbance decoupling problem by dynamic output feedback in the general case of systems with possible input-output feedthrough matrices. In particular,…
On the well-posedness in the solution of the disturbance decoupling by dynamic output feedback with self bounded and self hidden subspaces
Fabrizio Padula, Lorenzo Ntogramatzidis
This paper studies the disturbance decoupling problem by dynamic output feedback with required closed-loop stability, in the general case of nonstrictly-proper systems. We will sho…
The geometry of the generalized algebraic Riccati equation and of the singular Hamiltonian system
Lorenzo Ntogramatzidis, Augusto Ferrante
This paper analyzes the properties of the solutions of the generalized continuous algebraic Riccati equation from a geometric perspective. This analysis reveals the presence of a s…
A structural approach to state-to-output decoupling
Emanuele Garone, Lorenzo Ntogramatzidis, Fabrizio Padula
In this paper, we address a general eigenstructure assignment problem where the objective is to distribute the closed-loop modes over the components of the system outputs in such a…
