Description
Minimum actual speed for speed controller adaptation.
Speed controller gain and integration time can be adapted
according to actual speed
This is done by multiplying the gain
proportional gain) and integration time
integration time) by coefficients at certain speeds. The
coefficients are defined individually for both gain and
integration time.
When actual speed is below or equal to
min limit, the gain and integration time are multiplied by
Kp adapt coef at min speed
speed respectively.
When actual speed is equal to or above
max limit, no adaptation takes place (the coefficient is 1).
When actual speed is between
and 25.19 Speed adapt max
and integration time are calculated linearly on the basis of the
breakpoints.
