Stabilization of monotone control systems with input constraints
Till Preuster, Hannes Gernandt, Manuel Schaller
We present a stabilizing output-feedback controller for nonlinear finite and infinite-dimensional control systems governed by monotone operators that respects given input constrain…
Towards Polynomial Immersion of Port-Hamiltonian Systems
Mohammad Itani, Manuel Schaller, Karl Worthmann +1
Port-Hamiltonian (pH) systems offer a highly structured and energy-based modular framework for control systems. Many pH systems exhibit non-polynomial non-linearities. We consider…
Abstract second-order boundary control systems
Till Preuster, Timo Reis, Manuel Schaller
We consider abstract second order systems of the form , which are typically analyzed via the operator matrix $\mathcal{A}=\left[\begin{smallma…
Extension theory via boundary triplets for infinite-dimensional implicit port-Hamiltonian systems
Hannes Gernandt, Friedrich Philipp, Till Preuster +1
The solution of constrained linear partial-differential equations can be described via parametric representations of linear relations. To study these representations, we provide a…
Existence of solutions to port-Hamiltonian systems: initial value problems and optimal control
Willem Esterhuizen, Bernhard Maschke, Till Preuster +2
We investigate the existence of solutions of reversible and irreversible port-Hamiltonian systems. To this end, we utilize the associated exergy, a function that is composed of the…
