I'm no specialist on antenna control.
As I stated, I used a parabolic acceleration profile, so velocity
is cubic. The important thing is that the antennas can be driven
about efficiently without exciting nasty vibrations.
I suppose I should share my acceleration/velocity/position profiles
and we should look to see what the 48 ms interpolation scheme
makes happen.
Monday.
