Position Auto Tune
SVi1000 performs automatic determination
of the optimal valve position control param-
eters. In addition to P, I, D, the position algo-
rithm uses damping, symmetry for exhaust
and fill time constants, dead zone and mag-
nitude characterization parameters. Auto
Tune is optimized for 5% step changes with
negligible overshoot. After the Auto Tune
process is completed, the user can further
adjust the positioner tuning parameters to
more conservative or to more responsive
values.
