A nonlinear pursuit problem with discrete control and incomplete information

A two-person differential game is considered. The game is described by the system of differential equations $\dot x = f(x, u) + g(x, v)$, where $x \in \mathbb R^k$, $u \in U$, $v \in V$. The pursuer's admissible control set is a finite subset of phase space. The evader's admissible control set is a compact subset of phase space. The pursuer's purpose is to capture the evader, viz. system translation to any given neighborhood of zero. Sufficient conditions for the solvability of a capture problem in the piecewise open-loop strategies class are obtained. In addition, it is proved that the capture time tends to zero with the initial position approaching to zero. It happens independent of the evader's actions.
