The control problems of a space robot-manipulator in the process of mooring and docking with a geostationary satellite are considered when docking mechanism of the “rod-cone” class. A dynamic analysis is carried out with changing mooring conditions and the results of computer simulation are presented.

Methods have been developed for robust control of a space robot-manipulator during the in-flight maintenance of a geostationary communications satellite – replacement of fuel tanks, solar array panels and other replaceable components of the satellite attitude and orbit control system, which leads to significant changes in the inertial parameters of the hard clutch of a space robot with a geostationary satellite. The results of computer simulation for typical dynamic processes at such maintenance of a geostationary communications satellite are presented.

The possibilities of creating the control torques by clusters of flywheels and gyrodines when braking the rotation of a space robot mated with a geostationary satellite after the completion of their dockingare compared. The control system algorithms with unloading of electromechanical drives angular momentums using an electro-reaction propulsion unit are developed. The results of computer simulation of nonlinear dynamic processes are presented, confirming the effectiveness of the created algorithms.

Methods for guidance and motion control of a space robot during a flyby of a geostationary satellite at a visual monitoring its technical state are considered. Numerical results are presented that demonstrate the effectiveness of the developed discrete guidance and control algorithms.
