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…
Riesz bases of port-Hamiltonian systems
Birgit Jacob, Julia T. Kaiser, Hans Zwart
The location of the spectrum and the Riesz basis property of well-posed homogeneous infinite-dimensional linear port-Hamiltonian systems on a 1D spatial domain are studied. It is s…
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 .…
A Review on Realization Theory for Infinite-Dimensional Systems
Birgit Jacob, Hans Zwart
We give an introduction to the realisation theory for infinite-dimensional systems. That is, we show that for any function , analytic and bounded in the right half of the comple…
Zero Dynamics for Port-Hamiltonian Systems
Birgit Jacob, Kirsten A. Morris, Hans Zwart
The zero dynamics of infinite-dimensional systems can be difficult to characterize. The zero dynamics of boundary control systems are particularly problematic. In this paper the ze…
Equivalence between estimates for quasi-commutators and commutators
Hans Zwart
In this short note we show that under some mild conditions on the space and the operators, an estimate for needs only to be studied for invertible and e…
