ClearPath's RAS: Smoother Motion Control than S-Curves

Watch this TekTips tutorial to learn about Teknic's proprietary motion smoothing algorithm: Regressive Auto-Spline (or RAS for short). The RAS goes beyond traditional motion smoothing algorithms such as S-curving or cosine smoothing by limiting the jerk and the jerk-derivative resulting in incredibly smooth motion profiles. The video explains, in detail, what the RAS does graphically and uses a linear axis with a spring load to clearly illustrate the effect that the RAS has on a system.

Just come cross this video it’s nice and detailed explanation but you never competed RAS to S-Curves with for me is exactly this same thing just you use different name. S-profile have 7 characteristic also include smooth increasing or decreasing of acceleration. And torque curve looks like RAS,
can we have comet on this ?

Is it possible to do this with stepper killer motor type?

What does this do to coordinated moves in two or more axes on SD models?

wouldn't a pid control work just the same
