Abstract:
To avoid the singularity in the five-pyramid single gimbaled control moment gyroscopes system(SGCMGs),the dynamics of the five-pyramid configuration of SGCMGs are established.Based on the hyperbolic sine and piecewise function,robust coefficients are designed to improve the robust inverse steering law,which helps the SGCMGs get out of singularity with nonzero gimbaled angular velocity and avoid singularity rapidly and build more precise torque afterwards.The results of SGCMGs simulation with different torques and as the attitude maneuver of the flexible spacecraft show that the proposed steering law enables the SGCMGs to avoid singularity and build more precise torque later.
