I have created two scripts to aid with violin mode damping:

/opt/rtcds/userapps/release/sus/h1/scripts/violin_damping/filter.py

This is a GUI to aid in the creation of filter files for damping violin modes. Most notably it scripts the creation of the phase change filters for a given frequency. It is possible the method used here could be made more analytical, if someone has the time to look into how.

/opt/rtcds/userapps/release/sus/h1/scripts/violin_damping/settings.py

This is a GUI to aid in selecting the DOF, phase, and gain for damping violin modes. Most notably it turns on the correct combination of filter modules for a given phase, assuming that the filter modules are in the banks set by the filter.py script.

More details are in the comments at the top of each script.


I have also attached a log of the settings I have found to date for each frequency. These still need to be verified.
