Control of momentum control system according to the angular momentum gyroscopes for the control of the position of a satellite

摘要

Control moment gyros in an array (32) are rotated to reorient a satellite (11). Gyro angle is selected from one of three values based upon whether the stored angular momentum for the desired angle is below a singularity free value, greater than the singularity free value or is greater than the maximum available stored angular momentum.
