Identification data for Linear Direct Drive Forces compensation

<p>Linear direct drive forces are identified for compensation, where a linear direct drive is mounted in parallel to a ball screw feed drive axis.</p>

<p>Please refer to <a href="https://darus.uni-stuttgart.de/file.xhtml?persistentId=doi:10.18419/darus-2563/12">Readme.md</a> contained in the dataset for more detailed information.</p>

<p>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.</p>

<p>Contained measurements are:</p>
<ul>
<li>LDD_Transfer_function_Force_controlled.csv ... PRBS on linear direct drive current/force controlled for identification of its dynamics</li>
<li>SP_ ... constant velocity with different velocities (named in mm/s) forward (positive axes direction) and backwards (negative axes direction)</li>
<li>validate_SP ... constant velocity motion with compensation turned on to measure remaining forces and postiion errors</li>
</ul>
