I am looking to hold a value in a PID loop.
The application is i am running x amount of liters through a flow meter...my loop is perfect and i am flowing bang on...the system goes into recirc mode..meaning i dont want any of my liquid to flow..so my valve closes and my pump shuts down...now it goes out of recirc mode and it takes a min or two for the PID loop to fall in line..meaning i could get 30l per min rather that 15 l per min for a little bit...
what i would like to do is close the valve but keep the drive running at the same speed...so now my flow rate would be 0 but i want to freeze the 4x register going to the analog out..
any suggestions?
