FIELD: space engineering; on-board control equipment for cryogenic stages with cruise rocket engines. SUBSTANCE: proposed method includes prediction of cryogenic stage motion parameters at moment of cutoff of cruise engine. These parameters are used for determination of deviation of radius-vector and radial velocity of center of mass of cryogenic stage from their magnitudes in preset orbit. Then control correction signals are formed by angle and angular velocity of cryogenic stage in pitching channel. Pitch angle correction signal is limited at preset level. Then pitch velocity correction signal is changed in proportion to level of limitation and in reverse proportion to pitch angle correction signal. Limitation of magnitudes of corrections compensate for disturbance effect of abrupt change in control program on cryogenic stage dynamics. EFFECT: reduction of level of disturbances in angular stabilization circuit at retained quality of transient processes. 10 dwg
