A Low Voltage Controller for a Chaotic Micro Resonator
Bibliographic record
Abstract
The performance of a chaotic micro resonator is improved by redesigning a quadratic controller reported in a previous study. The chaotic micro resonator is composed of an electrostatic actuator and a voltage regulator (controller). The actuator is made of cantilever beam electrode above a fixed electrode. The actuator voltage, and consequently the electrostatic force magnitude, is controlled to drive the cantilever beam oscillations into chaos by creating a bi-stable regime in the system response. The performance of the redesigned controller is improved such that the system input voltage is reduced. The voltage generated by the controller is halved and the controller gains are smaller, which reduces the power and gain demands on the analogue controller components. The static and dynamic responses of the chaotic oscillator are studied and the sizes of the basins of attraction are compared for the improved and the original quadratic controllers. The controller can be configured to create two potential wells. The excitation DC voltages can then be adjusted to control the size of the upper and lower wells and thereby the basins of attraction around the two stable equilibria. As a result, one can shape the chaotic attractor to meet desired criteria. The reported chaos is intermittent chaos located in the lower well and between the two potential wells. This study can be used to design a new generation of nonlinear oscillators targeting high resolution sensors.

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.
