Ti
I component
Function: Y =
∫ Xd dt
Ti is the integration or floating time. It is the time that expires until the controller output has run through
the entire correcting range.

Characteristics:
A purely I controller completely eliminates the effects of disturbances. It thus has a favourable static
behaviour. Because of its finite correcting speed, it works more slowly than a P controller and tends to
oscillation. It is hence dynamically relatively unfavourable.
