“…Besides, there is another advantage of the scissored configuration, namely, the total angular momentum of the SGCMGs remains zero when the gimbal angles are zero, and the rotors are initially spun up, which does not induce unwanted gyroscopic torque. Thus, the scissored pair of SGCMGs is applied to various fields, such as attitude control of the Skylab Astronaut Maneuvering Research Vehicle 22 and the Japanese satellite ASTRO-G, 23 joint actuation of space robotics, 17,19,20 and human balance assist. 24 In this study, a scissored pair of SGCMGs is adopted as the attitude actuator of the reentry vehicles, related work of which has not been found currently.…”

A novel roll-channel attitude control scheme using a combination of single-gimbal control moment gyros and a reaction control system is proposed, providing sufficient control torque during the whole reentry process. A scissored-pair configuration is applied to the single-gimbal control moment gyros, which guarantees control torque exclusively along the roll axis and avoids internal singularity. A sliding-mode attitude controller is proposed to meet the requirements of rollchannel attitude stability and disturbance rejection. To obtain an optimal allocation of the commanded torque to the single-gimbal control moment gyros and the reaction control system, an allocation method based on fuzzy reasoning is proposed. To render the design and validation of the control scheme close to reality, the responsiveness of the singlegimbal control moment gyro is considered, and the discrete and delay properties of the reaction control system are included. The steering logic of the single-gimbal control moment gyro and the modulator of the reaction control system are designed, respectively. Numerical simulation is performed to verify the proposed control scheme. Moreover, a hardware-in-the-loop simulation system based on an air-bearing test bed is developed to conduct experiments for convincingly validating the proposed attitude control method. The feasibility and good performance of the proposed control scheme are verified by the results of the numerical simulation and the experiment.

“…In the 1960s, the US devoted itself to the research and development of DGCMGs. In 1973, three orthogonally mounted DGCMGs were firstly employed on NASA's Skylab as the main actuator [ 9 – 11 ], and four parallel mounted DGCMGs were applied on the International Space Station (ISS) in 1998 [ 12 – 14 ]. Up to the present, DGCMGs have been successfully employed for a variety of space missions.…”

Abstract:Integrating the advantage of magnetic bearings with a double gimble control moment gyroscope (DGCMG), a magnetically suspended DGCMG (MSDGCMG) is an ideal actuator in high-precision, long life, and rapid maneuver attitude control systems. The work presented here mainly focuses on performance testing of a MSDGCMG independently developed by Beihang University, based on the single axis air bearing table. In this paper, taking into sufficient consideration to the moving-gimbal effects and the response bandwidth limit of the gimbal, a special MSDGCMG steering law is proposed subject to the limits of gimbal angle rate and angle acceleration. Finally, multiple experiments are carried out, with different MSDGCMG angular momenta as well as different desired attitude angles. The experimental results indicate that the MSDGCMG has a good gimbal angle rate and output torque tracking capabilities, and that the attitude stability with MSDGCMG as actuator is superior to 10 −3°/ s. The MSDGCMG performance testing in this paper, carried out under moving-base condition, will offer a technique base for the future research and application of MSDGCMGs.
