Dear in video in 2:27 you said the goal is too cool down the hot water but the feed back sensor is measuring the temperature for the outlet of cooled water so i think the goal is to heat up the cooled water or the second drain in the right is for the hot water and left drain is for cooled water sorry for disturb just i wnt to insure my uderstatnding
That is a good observation. It could be either to cool down hot water or else heat up cold water. The outlet temperature of the cold stream is measured so it makes sense that you would be controlling that stream temperature instead.
Thank you for these great videos! I have two question about feedforward control implementation: 1) is there any lecture or book that you would suggest explaining when to use additivie vs multiplicative feedforward control when combining feedback and feedforward signals? 2) The other topic that I am very interested to learn more is about scaling that is needed for the feedforward control signal (for additivie combination), if the feedback controller is postion mode vs velocity mode. I would really appreciate if there is any resource that you would suggest to learn more about this?
Multiplicative feedforward may be applicable to highly nonlinear systems but is not commonly used in practice. I recommend each vendor's documentation to give details on the various PID implementations. There is Honeywell A, B, C, Allen Bradley, and other customized methods.
They are similar but different. An observer is typically an analytic solution to any process model or disturbance model. A feedforward controller is typically just a feedforward gain. apmonitor.com/pdc/index.php/Main/FeedforwardControl
Feedforward control is almost always used as an addition to feedback control. The employment prescreening doesn't necessarily fit the description of feedforward but it is similar.
Here are some resources: cache.org/teaching-resources-center/process-control There may be a textbook translated in your language such as Process Dynamics and Control by authors Seborg, Edgar, Mellichamp, Doyle. My online process control course has many TH-cam videos that may have foreign language sub-titles (apmonitor.com/pdc).
man I miss ap monitor videos! they help me a lot now that I'm graduated and have a job. thanks Dr Hedengren!
+GiantAnteatersRkool, I'm glad that you enjoy them. Keep in touch, especially if you make your way back to Provo.

Thankyou so much, these videos have been very useful for my assignment/exam revision

is feed forward control and disturbance observer based control the same concept?
They are similar but different. An observer is typically an analytic solution to any process model or disturbance model. A feedforward controller is typically just a feedforward gain. apmonitor.com/pdc/index.php/Main/FeedforwardControl
Is the drug test or the background check a feedforward control?
Feedforward control is almost always used as an addition to feedback control. The employment prescreening doesn't necessarily fit the description of feedforward but it is similar.
@@apm One time I had this question in a test about if the drug test is a feedforward, process, concurrent, or feedback control.
@@Allokee87 I would answer that it is feedforward but employment doesn't seem that a control loop.
In which book can I find more information?
I barely speak english..
