    • A method is adapted for slewing a body from an initial state to merge with a desired state profile. In an embodiment, the method includes the steps of (a) obtaining data indicative of a time profile of desired future states for the body; (b) searching sequentially through the time profile of desired future states; (c) calculating several slews for the body from the initial state to each of the desired future states; (d) determining the earliest future state to which the body can actually slew; (e) choosing the minimum-energy slew to that state; and (f) causing the body to perform that chosen slew.
    • 一种方法适于从初始状态回转身体以与期望的状态轮廓合并。 在一个实施例中,该方法包括以下步骤:(a)获得指示身体所期望的未来状态的时间曲线的数据; (b)按顺序搜索期望未来状态的时间曲线; (c)从初始状态向每个期望的未来状态计算身体的几个压摆; (d)确定身体实际可以摆脱的最早的未来状态; (e)选择最低能量回转到该状态; 和(f)使身体执行所选择的旋转。
