Stochastic port--Hamiltonian systems
In the present work we formally extend the theory of port--Hamiltonian
systems to include random perturbations. In particular, suitably choosing the
space of flows and effort variables we will show how several elements coming
from possibly different physical domains can be interconnected in order to
describe a dynamics perturbed by general semimartingale. In this sense the
noise does not enter the system solely as an external random perturbation but
each port is a semimartingale in itself. We will show how the present
treatment, extend pseudo-Poisson an pre--symplectic geometric mechanics. At
last, we will show that a power preserving interconnection of stochastic
port--Hamiltonian system defines again a stochastic port--Hamiltonian system
