In this paper, contrary to the past studies that treated the fixed skew angle for pyramid type CMGs systems, an adaptive skewing pyramid type CMGs (ASCMG) is proposed, in which the skew angle is treated as a variable to obtain larger toques. For this CMG system, a steering control law is proposed, which handles not only gimbal but also the skew angle. The proposed control law consists of pseudo-inverse term and null motion term. Numerical simulations show that the skew angle automatically changes in order to shorten settling time of the maneuver, and to avoid singularities, and returns to the ordinary angle, that is, β = 54.73[deg], at the end of maneuver.
