Abstract
The Large Adaptive Reflector is the Canadian concept for a new type of large-scale radio telescope. This new telescope is composed of a reflector made of individually actuated panels and a multi-tethered feed platform held aloft by an aerostat. The present thesis focuses on the position and orientation control of the feed platform. In the first part of the thesis, a model of both the cable and the feed platform are derived. Then, a control fully adapted to the particular system's dynamics is designed. This control strategy is based on the cascade control technique. The inner control loop adjusts the tension in each cable. The inner loop controller is synthesized using Hinfinity optimal control technique. In addition, gain scheduling is used to adapt the Hinfinity optimal controller to the cable properties. The outer control loop corrects the pose of the feed platform. To do this, control techniques such as Inverse Dynamics Control, PID controller and Hinfinity robustness analysis are used. Then, the model derived previously is connected to the multi-loop controller. Simulation is run and the control strategy performance level is calculated from simulation results.

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 it
