◎

Adaptive Mapping

Correlation-based PRBS identification builds an accurate CD response matrix without operator input.

⟳

Shrinkage Model

Polynomial edge-shrinkage estimation keeps actuator-to-databox alignment correct across the sheet.

▤

MPC Control

Model-predictive supervisory control flattens the profile using the learned footprint and gain.

⚡

Wander Feed-Forward

FFT-based frequency detection anticipates sheet wander and compensates one scan ahead.
