Optimzing servo control through an adaptive non-linear algorithm

Servotronix has developed an adaptive non-linear control algorithm, called HD Control, that minimizes tracking error and setline time better than competitor drives. A gantry robotic application, for example, required a sustained accuracy of 2 3 micrometers at maximum speed. Use of the CDHD servo drive with the HD Control algorithm increased the maximum application speed from 120 mm/s to 160 mm/s while maintaining the required accuracy, and resulted in a 33% increase in machine throughput. At a speed of 160 mm/sthe CDHD drive clearly achieved a higher accuracy and a lower ripple than a competitor’s servo drive.
