ABSTRACT:
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).
