Aerospace Instrument-Making Annotation << Back Optimal control of spatial orientation of a spacecraft with use of prognostic model M.V. Levskii The problem of optimal control of a three-dimensional reorientation of a spacecraft is considered. The functional that has a meaning of the propellant consumption is minimized. It is shown, that the optimal solution belongs to a class of two-impulse control at which spacecraft turn is executed as free (unguided) motion. For increase of accuracy of spacecraft’s move into the given angular position, the ways of control realizing a method of free trajectories are offered. The synthesized controls are invariant to external indignations and parametrical deviations. Results of mathematical modeling demonstrating high profitability of designed algorithms of control are presented.
