On stochastic port-hamiltonian systems with boundary control and observation

Stochastic port-Hamiltonian systems on infinite-dimensional spaces governed by Ito stochastic differential equations (SDEs) are introduced and some properties of this new class of systems are studied. They are a stochastic counterpart of boundary controlled port-Hamiltonian systems. The noise process is modelized as a Hilbert space-valued stochastic integral w.r.t. a Wiener process. The theory is illustrated on an example of a vibrating string with an element of randomness.
