Dissipativity properties of a class of nonlinear time-delay systems via Bessel-Legendre inequalities
Ikram El Haskouki, Hannes Gernandt
Time delays are inherent in many physical and engineered systems and can significantly affect their stability and performance. In this work, we investigate the dissipativity of a c…
Delay-dependent passivity and stability of linear port-Hamiltonian systems
Ikram El Haskouki, Hannes Gernandt
We study delay-dependent and independent passivity properties of linear port-Hamiltonian systems with delay terms. We derive passivity conditions using a particular storage functio…
A Port-Hamiltonian Modeling Approach for Integrated Hydrogen Systems
Abdullah Shahin, Hannes Gernandt, Anton Plietzsch +1
Hydrogen's growing role in the transition towards climate-neutral energy systems necessitates structured modeling frameworks. Existing gas network models, largely developed for nat…
Exact Time-Varying Turnpikes for Dynamic Operation of District Heating Networks
Max Rose, Hannes Gernandt, Timm Faulwasser +1
District heating networks (DHNs) are crucial for decarbonizing the heating sector. Yet, their efficient and reliable operation requires the coordination of multiple heat producers…
