Hinze, Christoph, 2023, "Replication Data for: Increasing the Dynamic Accuracy of Ball Screw Drives with Quasi-Sliding-Mode (qSMC) Position Control", https://doi.org/10.18419/DARUS-3292, DaRUS, V1
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... |

Hinze, Christoph, 2022, "Identification data for Linear Direct Drive Forces compensation", https://doi.org/10.18419/DARUS-2563, DaRUS, V1
Linear direct drive forces are identified for compensation, where a linear direct drive is mounted in parallel to a ball screw feed drive axis. Please refer to Readme.md contained in the dataset for more detailed information. Nut forces are measured via 4 parallel KISTLER force sensors in the nut. Total force is in `F_nut_sum`. Note, that the senso... |
