Finding the nearest passive or non-passive system via Hamiltonian eigenvalue optimization
Antonio Fazzi, Nicola Guglielmi, Christian Lubich
We propose and study an algorithm for computing a nearest passive system to a given non-passive linear time-invariant system (with much freedom in the choice of the metric defining…
A gradient system approach for Hankel structured low-rank approximation
Antonio Fazzi, Nicola Guglielmi, Ivan Markovsky
Rank deficient Hankel matrices are at the core of several applications. However, in practice, the coefficients of these matrices are noisy due to e.g. measurements errors and compu…
Generalized algorithms for the approximate matrix polynomial GCD of reducing data uncertainties with application to MIMO system and control
A. Fazzi, N. Guglielmi, I. Markovsky
Computation of (approximate) polynomials common factors is an important problem in several fields of science, like control theory and signal processing. While the problem has been…
A Gauss--Newton iteration for Total Least Squares problems
Dario Fasino, Antonio Fazzi
The Total Least Squares solution of an overdetermined, approximate linear equation minimizes a nonlinear function which characterizes the backward error. We show tha…
