Abstract

fetched live from OpenAlex

Differential actuation for electrostatic torsional mirror control has the advantage of torque amplification and linearization of the actuation voltage curve. However, this is achieved at expense of a reduced stability range. Furthermore, the linearization is valid only for small deflections, when an open-loop control scheme is used. This work presents a nonlinear closed-loop control in order to obtain stable operations and linearized input-output responses in the whole range of deflection. It is also shown that differential actuation makes it possible to circumvent the uncontrollability of the system at the flat position, allowing the micro-mirror to swing through this point with continuous bounded control. The simulation results show the strength and the performance of the proposed control scheme.

Teacher imitation

Not 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.
