  In this paper, we consider nonlinear PDEs in a port-Hamiltonian setting based
on an underlying jet-bundle structure. We restrict ourselves to systems with
1-dimensional spatial domain and 2nd-order Hamiltonian including certain
dissipation models that can be incorporated in the port- Hamiltonian framework
by means of appropriate differential operators. For this system class,
energy-based control by means of Casimir functionals as well as energy
balancing is analysed and demonstrated using a nonlinear Euler-Bernoulli beam.
