I need some information about control loop for process with very high transportation lag:
* CASE 1: the flow control element and the flow measure element are "separate" by a transportation lag of about 600 seconds.
* CASE 2: the flow control element and the current measure element (the current is quite proportional with flow rate but the ratio is
unknown) are "separate" by a transportation lag of about 600
The PID loop approach is not good, is it better a different control approach?
Thanks.
Best regards.
