Optimal guidance of the Isotropic Rocket in a partially uncertain flow field

摘要: In this paper, we address the problem of characterizing optimal strategy for guiding so-called Isotropic Rocket to a fixed target in presence partially known flowfield. We reformulate guidance into an equivalent two-player pursuit evasion game, where evader has modified vectogram. First, characterize strategies both players, assuming that is capturable. Then, derive necessary condition capture, and visualize capturability envelope using numerical simulations which compute level sets value function (isochrones). addition, consider more general case pursuer affected by friction (or drag). case, identify capture zones from geometric properties isochrones.
