Much attention has been paid on CMGs (Control Moment Gyros) as a large torque generator of spacecraft. There are many studies on singularities of CMGs. However, the steering law in their studies has achieved only singularity avoidance in most cases. In this paper, we propose a multi-objective steering law which achieves complete 3-axis attitude control while considering not only singularity avoidance but also another function. First, we introduce a steering law for both singularity avoidance and power optimization. Second, we propose another steering law for both singularity avoidance and achieving preferred gimbal angles. Regarding the control law, we apply a GS (Gain-Scheduled) controller via LPV control theory while introducing a Parameter-Dependent Coordinate Transformation.
