Abstract A controlled parabolic system that describes the heating of a given number of rods is considered. The density functions of the internal heat sources of the rods are not known exactly, and only the segments of their change are given. At the ends of the rods there are controlled heat sources and disturbances. The goal of the choice of control is to lead the vector of average temperatures of the rods at a fixed time to a given compact for any admissible functions of the density of internal heat sources and any admissible realizations of disturbances. After replacing variables, the problem of controlling a system of ordinary differential equations in the presence of uncertainty is obtained. Using a numerical method, a solvability set is constructed for this problem. Model calculations are carried out.
