Dynamic Gain Scheduling is available for the Ensemble Stand-Alone Multi-Axis Motion Controller and the Soloist Stand-Alone Single Axis Motion Controller.

Schedule Gains Dynamically Based on Threshold Values

Aerotech’s Threshold Gain Scheduling tool applies an algorithm that improves positioning performance and reduces cycle times by adjusting the servo-loop gains based on specific user-defined thresholds. If you go above or below certain threshold-values, the gains will adjust. Up to three levels of gains can be defined.

Threshold Gain Scheduling allows you to smoothly adjust gains based upon current or velocity. Simply pick multipliers for individual servo loop gains in the Dynamic Controls Toolbox GUI and enable these multipliers.
