Popis: | The problem of reentry vehicle control during its descent from a near-Earth orbit is considered under conditions of “enhanced” disturbances. The earlier developed terminal descent control algorithm is considerably improved to satisfy constraints on landing accuracy, load factor, and propellant consumption. A method for automatically shifting the deorbit point, adaptating to actual motion conditions, and modifying the reference bank function is proposed, which ensured the satisfaction of the specified constraints under action of an aggregate of enhanced disturbing factors. |
