Pulse-width Attitude Control of Large-scale Information Satellite at Service Modes*

Problems of nonlinear modeling, dynamic analysis and simulation of spatial motion by the large-scale information satellites with a flexible weak damping structure are considered. Obtained results on a multi-rate filtering of measurements and pulse-width control of the jet engines at the satellites’ service modes are presented. Results on analysis of the spacecraft nutation and flexible oscillations, and guidelines according to a logic in sequence of the gyrodine's rotors spin-up, are also represented.
