Abstract
The authors analyze the problem of approach of controlled objects in dynamic game problems. The sufficient conditions for the game termination in a finite guaranteed time are obtained when the classical Pontryagin condition is not satisfied. Instead of the Pontryagin selection, which does not exist, some shift function is considered. With its help, a special set-valued map** is introduced, which generates a lower resolving function. The latter plays a key role in formulating the result and allows constructing the control based on theorems of the Filippov–Castaing kind. A modified scheme of Pontryagin’s first direct method is proposed, which ensures a successful completion of the conflict-controlled process in the class of counter-controls. To compare the guaranteed times, the upper resolving function is introduced, and the corresponding scheme of the method is provided. The theoretical results are illustrated with a model example.
