论文摘要
本文考虑了在多个物理约束下的航天器态度跟踪的规定绩效控制（PPC），重点介绍了强大的问题。提出了一种新型的屏障Lyapunov函数，以实现在没有奇异性的角度限制下保证的绩效控制。此外，提出了针对性能功能的自适应策略，以软化约束，并在严重干扰后迅速重新稳定该系统，从而提供强大的鲁棒性。此外，辅助系统旨在处理输入饱和问题，并将执行器限制纳入系统。基于提出的结构，使用双层PPC框架相应地开发了回替台控制器。给出了数值模拟结果以验证所提出的控制器框架的效率和鲁棒性。8PA
This paper considers the prescribed performance control (PPC) of spacecraft attitude tracking under multiple physical constraints, focusing on the robust issues. A novel Barrier Lyapunov function is proposed to realize the guaranteed-performance control under angular velocity constraint without singularity. Additionally, an adaptive strategy for the performance function is presented to soften the constraint and quickly re-stabilize the system after severe disturbances occur, providing strong robustness. Further, an auxiliary system is designed to handle the input saturation issue, incorporating the actuator limitation into the system. Based on the proposed structure, a backstepping controller is developed accordingly using a double-layer PPC framework. Numerical simulation results are presented to validate the proposed controller framework's efficiency and robustness.8 pa
