ABSTRACT:
A method for avoiding singularities in the movement of a set of collinear CMGs in an array of CMGs in a spacecraft is provided. First, a command to adjust an orientation of the spacecraft is received. Then, the momentum needed from the set of collinear CMGs is determined. A dynamic control that determines a momentum path and avoids singularities by rotating the singularities out of the momentum path is used and a required gimbal movement for each of the CMGs in the set of collinear CMGs from the momentum path is calculated.
