Generalised inversion based maneuver attitude control for underactuated spacecraft

The methodology based on the concept of generalized inversion is investigated for asymptotic stabilization of underactuated rigid body dynamics under two degrees of actuation. Firstly, the underactuated kinematics and dynamics system is partitioned into three subsystems, and the underactuated subsystem is transformed as the point-wise linear form by differential geometry theory and achieves global realisability. Furthermore, with the introduction of dynamically scaled generalized inversion and perturbed null-control vector, a continuous feedback control law is designed to achieve the attitude stabilization of the underactuated spacecraft. Finally, the analytical and simulation results show that the proposed control methodology is effective.
