Data-driven adjoint-based calibration of port-Hamiltonian systems in time domain
Michael Günther, Birgit Jacob, Claudia Totzeck
We present a gradient-based identification algorithm to identify the system matrices of a linear port-Hamiltonian system from given input-output time data. Aiming for a direct stru…
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…
On Coercivity and the Frequency Domain Condition in Indefinite LQ-Control
Tobias Damm, Birgit Jacob
We introduce a coercivity condition as a time domain analogue of the frequency criterion provided by the famous Kalman-Yakubovich-Popov lemma. For a simple stochastic linear quadra…
Remarks on input-to-state stability of collocated systems with saturated feedback
Birgit Jacob, Felix L. Schwenninger, Lukas A. Vorberg
We investigate input-to-state stability (ISS) of infinite-dimensional collocated control systems subject to saturated feedback. Here, the unsaturated closed loop is dissipative and…
Noncoercive Lyapunov functions for input-to-state stability of infinite-dimensional systems
B. Jacob, A. Mironchenko, J. R. Partington +1
We consider an abstract class of infinite-dimensional dynamical systems with inputs. For this class, the significance of noncoercive Lyapunov functions is analyzed. It is shown tha…
On exact controllability of infinite-dimensional linear port-Hamiltonian systems
Birgit Jacob, Julia T. Kaiser
Infinite-dimensional linear port-Hamiltonian systems on a one-dimensional spatial domain with full boundary control and without internal damping are studied. This class of systems…
