A Variable Speed Control Moment Gyro (VSCMG) is a novel actuator for spacecraft attitude control and represents the future of current momentum exchange devices. The proposed concept consists of a spacecraft with a single VSCMG for attitude control: this particular actuator design is proposed for the purpose of high manoeuvrability with a minimal actuator configuration. The system under investigation is under-actuated and the full-attitude cannot be controlled. Based on this consideration, a reduced-attitude representation is proposed and exploited to control the spacecraft for pointing the bor...
