- Given an optimal control problem on a heterogeneous body with a periodical structure of particles depending on a small parameter e, we study the asymptotic behavior, as e converges to zero, of the optimal control functional and the optimal state when the initial problem is of parabolic type, and when on the particles' boundary, we assume a dynamic condition and the actuation of some controls for some subset of the particles. We show, in the so-called "critical case" (concerning a certain relation between the structure's period, the diameter of the balls, and the growth coefficient of the particles boundary condition), the appearance of some new non-local in time "strange terms", not only in the limit parabolic equation but also in the limit cost functional. Microscopic localized controls generate peculiar terms in both the limit equation and the cost functional that do not appear in the case of controls applied to the entire set of particles or when the boundary condition on the particles is of Robin type.
