Policies and controller design for a pursuing vehicle

Policies are developed for two pursuit-evasion differential games. In the first, the initial state is such that capture of the evader can be guaranteed. In the second, capture is not guaranteed, but the evader desires to approach a target as closely as possible. In both games, consideration is given to pursuer policies appropriate when the evader acts nonoptimally. A method is presented for designing simple state feedback controllers to realize the chosen policy.
