TMSY suspension damping and plant measurements

Bram, Valera, Matt

We made a few measurements of TMSY and got some damping loops running.  The attached plots show:

  1.  damping performance (REF plots are damping on)
  2. screen shot showing filters and gains
  3. plot of the damping filter used for all DOFs
  4. damping open-loop TF and plant TF for each DOF

We've left the damping loops on for a few days and they appear to be working well.
