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…
On continuity of solutions for parabolic control systems and input-to-state stability
Birgit Jacob, Felix Schwenninger, Hans Zwart
We study minimal conditions under which mild solutions of linear evolutionary control systems are continuous for arbitrary bounded input functions. This question naturally appears…
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…
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…
