Research on coordinated control method for stabilizing a coupling system after the spacecraft is captured

Two coordinated control methods, joint damping control and parameterised joint function coordinated control are proposed in this paper for stabilizing a spacecraft-captured coupling system based on conservation of angular momentum, for the coupling system may be unstable due to the change in mass characteristics and momentum of the coupling system. In these methods, management and re-distribution of angular momentum are used to stabilize the coupling system by planning and controlling the velocity of the flywheel and joints, the second method can be the hope of configuration, and is very convenient for on-orbit service. These methods using real flywheel as an actuator for momentum exchange are realizable in engineering. Simulation results show that these methods are effective.
