Adaptive Skewing Pyramid-type CMGs for Fast Attitude Maneuver

抄録

In this paper, an adaptive skewing pyramid-type control moment gyro (AS-CMG) is proposed, in which the skew angle is treated as an available parameter to obtain larger torques. This proposed AS-CMG can be categorized as either a single-gimbal CMG or a double-gimbal CMG, but not both. The AS-CMG is superior to the DGCMG due to its lightweight structure, and is superior to the conventional pyramid CMG with respect to maximum torque generated along the desired direction. The effectiveness of the proposed AS-CMG for fast attitude maneuvering, as compared to the conventional pyramid-type CMG with fixed skew angles, is demonstrated by numerical simulations.
