We study a finite horizon problem for a system whose evolution is governed by a controlled ordinary differential equation, which takes also account of a hysteretic component: namely, the output of a Preisach operator of hysteresis. We derive a discontinuous infinite dimensional Hamilton–Jacobi equation and prove that, under fairly general hypotheses, the value function is the unique bounded and uniformly continuous viscosity solution of the corresponding Cauchy problem.

We consider a model for the control of a linear network flow system with unknown but bounded demand
and polytopic bounds on controlled flows. We are interested in the problem of finding a suitable objective function
that makes robust optimal the policy represented by the so-called linear saturated feedback control.
We regard the problem as a suitable differential game with switching cost and study it in the framework of the viscosity solutions theory for Bellman and Isaacs equations.
