Information sets in the pulse control problem
The problem investigated is the following: A spatial vehicle (SV) must be guided towards a hazardous space object (HSO) (this kind of problem arises in many practical situations). It is assumed that the two objects are situated in the same plane and that they obey Kepler laws. In the course of the guidance process, one performs measurement of the angle sight of the SV, of the HSC and of the distance between them. Due to inherent errors, the goal is to minimize the misses. The control is of pulse type. To this end, one constitutes an information set containing the states compatible with the assumed task. A differential game in this set is constituted and a minimax problem is formulated. Through modeling, some numerical examples validate the proposed method. The paper is of interest for those working in the guidance control area.
