Abstract
The wheel speed of a VSCMG is allowed to change continuously. Consequently, a VSCMG can generate an attitude control torque about the wheel spin axis. The proposed control law is a hybrid method based on CMG and RW modes. Previously, RW mode in the VSCMG was basically used for singularity avoidance, and switching between CMG and RW modes for adjusting the attitude error at the terminal of maneuver was not enough smoothly. In the proposed steering law, to effectively activate RW mode at the terminal of maneuver, the condition number of the RW Jacobian matrix is calculated, then the weighting matrices for the steering control law are changed in accordance with not only the magnitude of attitude error, but also condition number. A numerical simulation is carried out to validate the proposed steering law.
