More stable regulation required
When the regulation is too fast, for example noisy curves, it may be necessary to optimize
the parameters in the opposite way, i.e., increase I parameter and decrease P parameter.

Consequence
The system will become unstable.
The system will respond slow to errors and possibly be
unable to eliminate errors completely.
The system will oscillate after the error has been elimi-
nated.
The system will be unable to eliminate errors completely.
The system will overshoot initally when regulating for
errors.
The system will be prevented from increasing the P-
component enough to achieve fast response without
resulting oscillations.
