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 sensors may drift and have to be referenced.
Contained measurements are:
LDD_Transfer_function_Force_controlled.csv ... PRBS on linear direct drive current/force controlled for identification of its dynamics
SP_ ... constant velocity with different velocities (named in mm/s) forward (positive axes direction) and backwards (negative axes direction)
validate_SP ... constant velocity motion with compensation turned on to measure remaining forces and postiion errors
Abbreviations used in data/metadata:
LDA/LDD ... linear direct drive
KGT/BSC ... ball screw drive
