I have created a directory under the svn. The link is https://nodus.ligo.caltech.edu:30889/svn/trunk/docs/haixing
In the directory, there are three folders are related to the magnetic levitation.
The experimental data is in the "experiment_data".
The comsol numerical modelling files are in "mag_levi_comsol_modelling" which contains "1x1 magnets",
"4x4 magnets" and "16x16 magnets" sub-folders where detailed modelling results are included.The mathematica
notebooks in those folders are used to produce the plots I posted on the wiki page.
The "mag_levi_feedback" contains the Simulink modelling of the feedback loop. To generate the plot for the
open-loop transfer function. One needs to ruc the "mag_lev.m" file.
