Hi All,
I would appreciate any advice/input on the below setup and proposal and value any feedback on best methods to achieve the intended outcome (if possible)
Pair of PI controllers, typical cascade loop, level (master) / flow (slave) - only unlike your typical cascade loop the priority is on maintaining a consistent feed flow to a downstream column and allowing the level in the surge vessel to swing. The surge vessels have sufficient capacity that in the event a disruption to the feed flow occurs the level is impacted but slowly. The flow into the vessel does vary only by small amounts during normal operation.
Has anyone successfully implemented a solution like this? was it simply a case of slowing down the level controller?
