This paper studies the attitude-tracking control problem of spacecraft considering on-orbit refuelling. A time-varying inertia model is developed for spacecraft on-orbit refuelling, which actually includes two processes: fuel in the transfer pipe and fuel in the tank. Based upon the inertia model, an adaptive attitude-tracking controller is derived to guarantee the stability of the resulted closed-loop system, as well as asymptotic convergence of the attitude-tracking errors, despite performing refuelling operations. Finally, numerical simulations illustrate the effectiveness and performance of the proposed control scheme.

考虑在轨加油的航天器自适应姿态跟踪控制

本文研究了考虑在轨加油的航天器姿态跟踪控制问题。建立了用于航天器在轨加油的时变惯性模型，该模型实际上包括两个过程：传输管中的燃料和储罐中的燃料。基于惯性模型，尽管执行了加油操作，但仍派生了自适应姿态跟踪控制器，以确保所得闭环系统的稳定性以及姿态跟踪误差的渐近收敛。最后，数值模拟说明了所提出的控制方案的有效性和性能。
