Flexible Structure Vibration Control Using Double-Gimbal Variable-Speed Control Moment Gyros
Bibliographic record
Abstract
This paper studies the dynamics and control of a flexible space structure using double-gimbal variable-speed control moment gyros (DGVSCMGs). The DGVSCMGs are mounted on the flexible structure as actuators for attitude and vibration control. A flexible structure with a cluster of angular momentum devices is considered to be a gyroelastic body. The detailed dynamics of a single gyroelastic body under the influence of the actuators is derived using Kane’s method. A simple controller capable of vibration suppression is proposed for the attitude maneuver. A novel steering law is designed for the DGVSCMGs. Null motion of the gimbal angles and rotor rates is considered to compensate for the undesirable modal force in the vibration equation. Numerical simulations are performed to verify the effectiveness of the proposed controller and steering law.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
