An adaptive control strategy based on backstepping control and direct adaptive control was proposed to resolve the flexible spacecraft attitude stabilization control problem. Firstly, the flexible spacecraft was divided into dynamics subsystem and kinematics subsystem, and an ideal reference model was designed. Secondly, under the assumption of small attitude angle, a direct adaptive intermediate control law was designed. Finally, the spacecraft attitude controller was designed by adopting the backstepping control method, and the stability of the close-loop control system was proved. Theoretical study and numerical simulation results validate the efficiency of the flexible spacecraft adaptive attitude stabilization controller. [ABSTRACT FROM AUTHOR]
