    • A system for controlling an aerospace vehicle using on-line inertia estimation may include an attitude sensor to measure an attitude of the aerospace vehicle. The system may also include a processor on board the aerospace vehicle. An inertia estimator operable on the processor may generate an on-line inertia estimate of the aerospace vehicle. A rate and attitude estimator operable on the processor may determine an angular position and angular velocity of the aerospace vehicle using the attitude measurement of the aerospace vehicle and the on-line inertia estimate for controlling movement and orientation of the aerospace vehicle without any rates of rotation of the aerospace vehicle being required.
    • 使用在线惯性估计来控制航空航天车辆的系统可以包括用于测量航空航天器的姿态的姿态传感器。 该系统还可以包括航空航天车辆上的处理器。 可在处理器上操作的惯性估计器可以产生航空航天车辆的在线惯性估计。 在处理器上可操作的速率和姿态估计器可以使用航空航天车辆的姿态测量值确定航空航天车辆的角度位置和角速度,以及用于控制航空航天车辆的运动和取向的在线惯性估计,而没有任何转速 的航空航天车辆。

    • A reorientation controller for a satellite includes a slew rate command generator that generates a slew rate command signal ({right arrow over (ω)}r—cmd) in response to an attitude error signal. The attitude error signal corresponds to the difference between an initial attitude and a target attitude. The slew rate command generator may introduce a phase lead (θL) into the slew rate command signal ({right arrow over (ω)}r—cmd). The controller may perform a spin phase synchronization when the target attitude is unsynchronized in spin phase with the initial attitude. The satellite may perform a reorientation maneuver in response to the slew rate command signal ({right arrow over (ω)}r—cmd).
    • 用于卫星的重新定向控制器包括:压摆率命令发生器,其响应于姿态误差信号产生转换速率命令信号({右箭头(ω)} r-cmd)。 姿态误差信号对应于初始姿态与目标姿态之间的差异。 转换速率命令发生器可以将相位引线(thetaL)引入转换速率命令信号({右箭头(omega)} r-cmd)。 当目标态度与初始姿态的自旋阶段不同步时,控制器可以执行自旋相位同步。 卫星可以响应于转换速率命令信号({right arrow over(omega)} r-cmd)执行重新定向机动。
