The problem of estimating the accuracy of control algorithms for a linear system on a finite time interval in the presence of initial and time-varying perturbations is considered from the standpoint of maximin testing methods. A method of forming the positional strategies of testing based on a modification of Krasovskii's method of extremal aiming is proposed. It is shown by an example that the convex reachable set of a control system has a multiextremal support function.
