RMC100 and RMCWin User Manual
4-50
o The Sum Error Squared decreased to 13,000!
o The overshoot disappeared.
o The Extend and Retract Feed Forwards are generally not the same for hydraulic systems.
The position is now tuned. To check that this will work at higher speeds, increase the Accel and
Decel to 300 and the speed to 40000. The plot (plot time = 1 sec) looks like this:
o The parameters work well for the higher speed (no lagging, overshoot or oscillation), and
will be left unchanged.
o The Sum Error Squared increased, but that is only because of the higher speed, which
inherently results in greater position errors.
