Regarding the oil refining production process, automatic PID control is used for loop operation
Thread Content
I have a question. We work in the field of oil refining processes, and our company requires a high level of automation – specifically, 98% automatic control for various control loops. I would like to know whether, for loops related to flow rate, pressure, level, and temperature, PI control is generally used? Are there any good methods for optimizing PID values? Under what circumstances should PID control be used? What effects do the values of P, I, and D have on the control loop? Could you explain this in detail? Thank you all? ? I’m a beginner, hehe
It’s hard to explain PID tuning in just a few words; I’ll upload Allen-Bradley’s parameter documentation. Is there anyone who will take a look?
The materials on the 3rd floor are very comprehensive, combining theory with practice!
In simple terms, complex control loops related to temperature require PID regulation; for ordinary single-loop control, P is sufficient, while for cascade control, PI generally meets the control requirements.
