The Rotary-Motion Extended Array Synthesis spacecraft is a dual-spin spacecraft with long tethers held in tension by the spin. This paper derives the free-space (not considering orbital effects) dynamics of this spacecraft, and it compares two controllers in performance and the effort expended. In contrast to prior work, one of the controllers used takes account of the tether motion rather than just considering the hub motion. The spacecraft is simulated performing a challenging task including an acceleration and 90 deg slew with both controllers. The controller that accounts for the tether motion uses $\sim 10\%$ less fuel while providing similar errors.

旋转运动扩展阵列合成航天器是一种双自旋航天器，长绳通过自旋保持在张力状态。本文推导了该航天器的自由空间（不考虑轨道效应）动力学，并比较了两种控制器的性能和所花费的精力。与之前的工作相比，所使用的控制器之一考虑了系绳运动，而不仅仅是考虑了轮毂运动。航天器被模拟执行具有挑战性的任务，包括使用两个控制器加速和 90 度回转。负责系绳运动的控制器使用$～10\%$ 更少的燃料，同时提供类似的错误。
