NDLI: Dynamic infinity-norm constrained control allocation for attitude tracking control of overactuated combined spacecraft

Content Provider	IET Digital Library
Author	Huang, Xiuwei Duan, Guang Ren
Abstract	In this study, a dynamic L ∞ (infinity-norm) constrained control allocation scheme is designed for attitude tracking control of combined spacecraft with inertia uncertainties and external disturbances. A disturbance-observer-based constrained backstepping control law is developed to generate the control command signals considering non-symmetric constraints on control input, where the lumped disturbance containing inertia uncertainties and external disturbances is compensated by the output of stable non-linear disturbance observer. The control scheme can guarantee that the attitude and angular velocity tracking error converge to small neighbourhood of zero by appropriately tuning the control parameters. With the consideration of physical amplitude and rate constraints on actuators, the dynamic L ∞ constrained control allocation problem is solved by linear programming technique. Numerical examples demonstrate the effectiveness of the proposed disturbance-observer-based constrained backstepping control method and the dynamic L ∞ constrained control allocation algorithm.
