Description
This setpoint is giving regulator integration factor. See Note below.
Note:
ID-Lite controllers include PI loop for speed or analog output regulation. The requested value is
given by setpoints
and
. This loop is working like
Proportional-Integral regulation with setpoints
and Reg Integral for each part and
these parts affect each other.
The controller output is given by:
Reg Gain * e(t) + Reg Integral * ʃ e(t) dt,
where e(t) is deviation of actual value e(t) = Request 1, 2 – Measured value.
Here are two tunning parameters that can be adjusted Reg Gain and Reg Integral. These parameters
interact each other, see the graphic below. Picture shows how differences in Gain and Integral can affect
PI loop’s responsiveness. The central pic is as base case with fast change with minimum oscillations to
required level. Upper left graph shows high gain and low integral values, what produce large oscillation
with slow smoothing. Opposite case is on the lower right graph, which shows low gain and high integral
values. The response of the system is sluggish.
