On the stability of port-Hamiltonian descriptor systems
Hannes Gernandt, Frédéric E. Haller
We characterize stable differential-algebraic equations (DAEs) using a generalized Lyapunov inequality. The solution of this inequality is then used to rewrite stable DAEs as dissi…

Port-Hamiltonian formulation of nonlinear electrical circuits
Hannes Gernandt, Frédéric Haller, Timo Reis Arjan van der Schaft
We consider nonlinear electrical circuits for which we derive a port-Hamiltonian formulation. After recalling a framework for nonlinear port-Hamiltonian systems, we model each circ…
