Hi Patmat,
Instead of a single point you could use a window
For example
If newvalue > oldvalue + 3 then speedup
If newvalue < oldvalue - 3 then speeddown
This implicates that if newvalue is within +/- 3 from oldvalue, speed is
maintained
Hope this helps

Hysteresis can be our friend, at least in certain control situations.
For example, I may have an adjustment knob (a pot) right on a spot
that causes a system to oscillate between two states (a step
function).
Question: How can you build hysteresis into a stamp program? I'm
reading a pulse width; once the pulse gets wider than X, I go from
one operating speed to another. I want to avoid juddering between the
two states.
