Model reduction with pole-zero placement and high order moment matching
Tudor C. Ionescu, Orest V. Iftime, Ion Necoara
In this paper, we compute a low order approximation of a system of large order that matches moments of order of the transfer function, at interpolation points, ha…

Optimal H2 moment matching-based model reduction for linear systems by (non)convex optimization
I. Necoara, T. C. Ionescu
In this paper we compute families of reduced order models that match a prescribed set of moments of a highly dimensional linear time-invariant system. First, we fully parametrize t…

Families of moment matching based, structure preserving approximations for linear port Hamiltonian systems
Tudor C. Ionescu, Alessandro Astolfi
In this paper we propose a solution to the problem of moment matching with preservation of the port Hamiltonian structure, in the framework of time-domain moment matching. We chara…
