A one-type control problem with a convex goal in case of disturbance

The authors analyze a one-type problem of positioning of a phase point at a preset time on the convex closed set with minimization of an integral of the convex by standards of control function. There is a disturbance in motion equations; the quantity of its norm is less than the predetermined number. The problem is analyzed within the theory of differential games. The authors prove the existence of an optimal control and give the algorithm of its plotting.
