Computational study demonstrates robust singularity transit in redundant control moment gyroscopes, indicating an effective spacecraft steering approach without explicit avoidance maneuvers.

Key Points

To develop a simple and effective steering logic that allows redundant single-gimbal control moment gyro systems to pass through and escape internal singularities.
Formulated a mixed two-norm and weighted least-squares minimization problem utilizing a singularity robust inverse with a nondiagonal weighting matrix.
Integrated deterministic dither signal generation to actuate gimbals when the control moment gyro system operates near singular configurations.
Demonstrated rapid transit through and escape from unavoidable internal singularities without requiring explicit singularity avoidance algorithms.
Preserved minimum two-norm pseudoinverse behavior under nominal conditions, though exact tracking of prescribed attitude trajectories is not maintained during singularity crossings.
