Description
This setpoint is giving regulator integration factor.
Note:
InteliDrive Lite controllers include PI loop for speed or analog output regulation. The requested
value is given by setpoints Request 1, 2. This loop is working like Proportional-Integral regulation with
setpoints Reg Gain and Reg Integral for each part and these parts affect each other.
Note:
The controller output is given by:Reg Gain * e(t) + Reg Integral * ʃ e(t) dt,
Note:
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.
