Comment to PR Pitch local control updated (Click here to view original report: 1914)

Attached is the designed OLTF of the previous and the new servoes on Dec 6th.

The phase mergin is about 40 deg. The difference of gain at above the UGF is about 10 dB.

Also, I have tried to look up the time the PR was resonating (at around 6/12/2019 6:00 UTC), but I could not find any DAQ signal for PR local damping loop.
Why don't we add some (if the storage allows)?
