Hello Taknavaz

 

The circuit that you have posted is an instumentation amplifier with a differential input and some high frequency role off where the role off gain is adjustable.

At low frequencies, this will provide proportional gain and at high frequencies it wil provide both proportional gain and integral gain.

 

It is not actually a PI controller, but it could constitute part of a PI controller.

 

Best regards,

Mark.
