Robust High Performance Framework for Spacecraft Earth-Observation Attitude Control

This paper focuses on the high-performance earth-observation attitude control problem, while some particular performance index needs satisfying. Moreover, the system response is required to be controlled precisely. In order to achieve this goal, we introduce our newly-proposed SAPPC scheme to this issue, building a complete framework that is feasible and applicable. By introducing the proposed SAPPC scheme into this issue, the controller can ensure that the state trajectory can track a reference trajectory that is designed according to the given performance requirement, and the accurate control of the system response can be realized in this way. Further, the predefined-time stability technique and the dynamic surface control technique is employed to enhance the controller’s robustness and performance, providing better characteristic to the proposed framework. Numerical simulations are presented to show the effectiveness of the proposed scheme.
