Design of the Robust Controller of the APT Fine Tracking System Based on the Structured Singular Value Theory
Bibliographic record
Abstract
APT (Acquisition, Pointing, Tracing) system is the important component of the space laser communication system, and its tracing accuracy is mainly determined by the fine tracing subsystem. To enhance the tracing accuracy and robustness of the APT system, the robust control technology based on the structured singular value theory ( integration) is adopted in the design of the controller of the APT fine tracing subsystem, and the mathematical model of the augmented object of the fine tracing subsystem based on integration is established, and the robust controller is designed by the D-K iterative method in this article, and the bandwidth of the fine tracing subsystem could achieve 318 Hz, which could satisfy the requirements of the APT system to the bandwidth of the fine tracing subsystem. The equivalent sine simulation of the system indicates that the system tracing accuracy is better than 0.6 µrad.

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.
