The parameters, PI top limit and PI bottom limit could be considered as the multiplier factor respectively
maximum and minimum of the feed-forward.
PI top limit = 1
PI bottom limit = 0
In this application the regulator uses a proportional-integral type of control.
The gains of the various components must be set with the load on the machine. A reference, it is possible to start
the test with the values below (default values):
Set PI P gain PID = 10%
Set PI I gain PID = 20%
Set PD P gain PID = 10%
If necessary, use the derivative component for forcing the regulator output during velocity changes of the system,
setting for example:
PD D gain PID = 5%
PD D filter PID = 20ms
If not necessary, keep these parameters = 0.
