Abstract
A differential game described by a nonlinear system of differential equations of order two is considered in a finite Euclidean space. The value set of the pursuer control is a finite set. The value set of the evader control is a compact set. The purpose of the pursuer is a translation of the system in a finite time to any given neighborhood of zero. The pursuer uses a piecewise open-loop strategies constructed only by using information on the state coordinates and the velocity in the partition points of a time interval. Sufficient conditions of the capture problem solvability in the piecewise open-loop strategies class are obtained. These conditions are imposed on the system vectogram at zero and have a geometric nature. Also, it is proved that the capture time tends to zero with the approach the initial position to zero. It happens independently of the evader’s actions. The solution of the problem is based on a positive basis notion.
