Kinetic description of optimal control problems and applications to opinion consensus

In this paper, an optimal control problem for a large system of interacting agents is considered using a kinetic perspective. As a prototype model, we analyze a microscopic model of opinion formation under constraints. For this problem, a Boltzmann-type equation based on a model predictive control formulation is introduced and discussed. In particular, the receding horizon strategy permits to embed the minimization of suitable cost functional into binary particle interactions. The corresponding Fokker-Planck asymptotic limit is also derived and explicit expressions of stationary solutions are given. Several numerical results showing the robustness of the present approach are finally reported.
