One DGVSCMG can achieve 3-axis attitude control of a spacecraft. However, in attitude control problems, it is difficult to avoid singularities of a DGVSCMG system when there is no redundancy. In this paper, we develop a singularity robust controller to avoid singularities of the system. This technique considers singularity avoidance by not a steering law but a control law while introducing an extra term into the Lyapunov function. Through a numerical simulation, effectiveness of the singularity robust controller is demonstrated.
