If KPROP is increased too far,
overshoot or ringing will occur. The
plot opposite shows the effect of
setting KPROP to a value of 7.
This overshoot and/or ringing can
be reduced by introducing a
damping term - either KVEL or
KDERIV...
7. The plot opposite shows how
applying a v alue of 0.25 to KVEL
(with KPROP set to 4.7), causes a
response with a small overshoot but
which settles quickly.
The ideal response is to have a
sharp (square) response with very
little overshoot and no oscillations.
The Step Response Statistics tab
shows measured values which can
be used as a further guide to tuning.
