How to add Intergral control to P controller for temperature

[Oggi1180]

Hello All,

I am required to add integral control to the attached block diagram,

It currently only contains Proportional control.

Any help would be much appreciated.

Hi Oggi,

the integral part of a PID control integrates the error term over time, so you need to calc the error and add it to the value in a shift register.

Why don't you use the PID functions coming with LabVIEW?
