Abstract
To increase the dynamics of ball screw drives, a nonlinear position controller, based on sliding-mode control, is presented together with its parameterization for robust stability. The controller is validated experimentally on a ball screw axis and shown increase the controller bandwidth from 8 Hz to 15.9 Hz in comparison to P position control with feedforward, to reduce the mean absolute tracking error under static high performance cutting forces by 24 % and to be robustly performant with a maximum degradation of the tracking error of 2.7 % for variations of 20 % in the model parameters. Please refer to Readme.md contained in the dataset for more detailed information.
