On BIBO stability of infinite-dimensional linear state-space systems
Felix L. Schwenninger, Alexander A. Wierzba, Hans Zwart
In this paper we consider BIBO stability of systems described by infinite-dimensional linear state-space representations, filling the so far unattended gap of a formal definition a…
Symplectic model order reduction of port-Hamiltonian systems
Silke Glas, Mir Mamunuzzaman, Hongliang Mu +1
This work proposes a novel structure-preserving model order reduction (MOR) method for linear, time-invariant port-Hamiltonian (pH) systems. Our goal is to construct a reduced orde…
Observability for port-Hamiltonian systems
Birgit Jacob, Hans Zwart
The class of port-Hamiltonian systems incorporates many physical models, such as mechanical systems in the finite-dimensional case and wave and beam equations in the infinite-dimen…
Stabilization of port-Hamiltonian systems by nonlinear boundary control in the presence of disturbances
Jochen Schmid, Hans Zwart
In this paper, we are concerned with the stabilization of linear port-Hamiltonian systems of arbitrary order on a bounded -dimensional spatial domain .…
Port-Hamiltonian descriptor systems
Christopher Beattie, Volker Mehrmann, Hongguo Xu +1
The modeling framework of port-Hamiltonian systems is systematically extended to constrained dynamical systems (descriptor systems, differential-algebraic equations). A new algebra…
Linear wave systems on -D spatial domains
Mikael Kurula, Hans Zwart
In this paper we study the linear wave equation on an -dimensional spatial domain. We show that there is a boundary triplet associated to the undamped wave equation. This enable…
Feedback theory extended for proving generation of contraction semigroups
Mikael Kurula, Hans Zwart
Recently, the following novel method for proving the existence of solutions for certain linear time-invariant PDEs was introduced: The operator associated to a given PDE is represe…
De Branges-Rovnyak realizations of operator-valued Schur functions on the complex right half-plane
Joseph A. Ball, Mikael Kurula, Olof J. Staffans +1
We give a controllable energy-preserving and an observable co-energy-preserving de Branges-Rovnyak functional model realization of an arbitrary given operator Schur function define…
