    • A vibration reduction system (40) is provided for use in conjunction with a rotational device (10 including a stationary body (12), a rotating body (18), and a first bearing assembly (32) disposed between the stationary body and the rotating body. The vibration reduction system includes a first plurality of bearing mount actuators (52, 72, 74) residing between the stationary body and the first bearing assembly. The first plurality of bearing mount actuators is configured to adjust the radial position of the first bearing assembly. The vibration reduction system further includes a vibration sensor (44, 80, 82), which is coupled to the stationary body, and a controller (46), which is coupled to the vibration sensor and to the first plurality of bearing mount actuators. The controller is configured to reduce vibrations sensed by the vibration sensor by selectively adjusting the radial position of the first bearing assembly utilizing the first plurality of bearing mount actuators.

    • Apparatus, Systems, and Methods are provided for controlling motion of a spacecraft (100). One apparatus includes a non-contacting actuator (3210) and a passive mechanical system (310) coupled in parallel with one another. A system includes a payload (110), a bus (120), and a hybrid actuator (300) including a non-contacting actuator and a passive mechanical system coupled in parallel, and coupled between the bus and the payload. The system also includes an inertial actuator (1210) configured to maneuver the bus to maintain a relative position and/or attitude of the bus with respect to the payload. One method includes receiving a signal instructing a first controller (2320) to change the position and/or attitude of a payload and utilizing a hybrid system to change the position and/or attitude of the payload. The method also includes receiving the signal at a second controller (2205) and utilizing a system to change a position and/or attitude of the bus independent of the payload.
    • 提供装置,系统和方法来控制航天器(100)的运动。 一种装置包括彼此并联连接的非接触致动器(3210)和无源机械系统(310)。 系统包括负载(110),总线(120)和混合致动器(300),其包括并联耦合的非接触致动器和无源机械系统,并且耦合在总线和有效载荷之间。 该系统还包括惯性致动器(1210),其被配置为操纵总线以保持总线相对于有效载荷的相对位置和/或姿态。 一种方法包括接收指示第一控制器(2320)改变有效载荷的位置和/或姿态并利用混合系统来改变有效载荷的位置和/或姿态的信号。 该方法还包括在第二控制器(2205)处接收信号,并且利用系统来独立于有效载荷来改变总线的位置和/或姿态。
