"your controller is not able to get in your pv close to setpoint, that's what we call it reset wind up" 5:59 I'm a bit disappointed with this explanation. I understand that the main subject of the video is not windup, but this phrase is just wrong and there are important things to mention when talking about windup. The first thing to say is that windup is only related to the integral part of a PID, the "I" part. A P or PD control doesn't have that problem. Second, windup is related to output saturation. For example, if the PID calculation has an output of 150% open for a control valve, the control valve can only be 100% open. Saturation is probably why you are connecting the BKCAL_OUT of the AO block to the BKCAL_IN of the PID block, to let the PID block know that the calculated output is not achieved by the AO block. With windup the controller is still able to get close to the setpoint, but it will take much longer to do so and it can cause the PV to reach undesirable values for some time.
Thank you for the tutorial. I have a question if you don't mind. Where do I specify in the DeltaV program if this controller valve is a safe fail open or safe fail close? Thank you again
Best explanation
Welcome the way he explain his concepts.
how effective training video .Thanks
great lecture my frind thanks a lot
Very interesting and detail
Nice lecture sir

I thought you will actually program the PID controller. You just connected the boxes. It is really easy.
thank you
Thanks for sharing
How I can simulate controller in VBA excel?
Which program you are using for simulation?
plz kindly make your video quality Good its Blur.

How to programming
DeltaV not the DCS ,it is OCS .
