Abstract: Some results of computer modeling of a flexible spacecraft dynamics with low-frequency elastic oscillations of construction are presented. Three types of algorithms for gyro-force control of the spacecraft are considered: proportional, proportional-differential, and proportional-integrated. Areas of preferable use of these control algorithms (by criterion of control time minimum) are determined at change of the lowest frequency of construction elastic oscillations.

Keywords: flexible spacecraft, computer modeling, algorithms, gyro-force attitude control.
