Abstract
This paper describes a robust mixed-synthesis controller for shape memory alloy (SMA) actuators. The weights for the controller are chosen such that the disturbance rejection criterion is met for low frequencies and robust stability is maintained for high frequencies. Simulation and experimental results show fast and accurate response for strain in the SMA under no perturbation. The performance of the controller is also verified in the presence of load and cooling rate perturbations. The response shows that the controller maintains good disturbance rejection and robust stability. Sinusoidal references are tracked with negligible error in the presence of perturbations. In addition, the controller is also tested for SMA actuators operating in water. The excellent results validate further both the model and the controller used for the SMA actuators

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
