Integral (I) action time of the PID controller (P-CHAN-00822)

P-CHAN-00822

Integral (I) action time of the PID controller

Description

This parameter weights the I component of the PID controller. The integral action time defines the time after which the P and I components of the manipulated variable are equal.

A large integral action time produces greater control stability. The shorter the integration action time, the greater the I component and the faster the control.

Disable the I component by i_tn = 0.

Parameter

dist_ctrl[i].i_tn (where i=0)

Data type

REAL64

Data range

0.0 <= i_tn <= 50.0

Dimension

[s]

Default value

0.0

Remarks

Available as of Build V3.1.3080.12 or V3.1.3107.44

To begin with, it is advisable to select a high initial value for the integral action time setting (e.g. 5) to avoid instability in the control loop. You can then reduce the integral action time step by step to obtain the effect you require. If there are no permanent control deviations, do not use the I component at first.
