Combined Spacecraft Attitude Tracking Control with Prescribed Performance via A Fully Actuated System Approach

In this paper, a fully-actuated system prescribed performance controller is proposed to achieve attitude tracking control of the combined spacecraft. In order to make the combined spacecraft satisfy the required steady-state and transient performance in the attitude tracking control process, a fully actuated system controller with prescribed performance is proposed. The attitude dynamics model of the combined spacecraft is transformed into a tracking error function. Furthermore, the controller of the fully actuated system is designed according to the error function to realize the attitude tracking control of the combined spacecraft. Lyapunov function is introduced to prove the stability of the system. With the presented way of designing fully actuated system prescribed performance controller, the numerical simulation results verify the effectiveness of the proposed method.
