Behavior of the controller
|
---|---|
lag_neg = 0 and lag_pos > 0
|
The controller works as if it had only a negative feedback with time constant lag_pos.
|
lag_pos < lag_neg > 0
|
The controller works as if it had only a negative feedback with time constant lag_neg.
|
xf_man < 0 or xf_man > 100
|
The controller works without internal feedback paths.
