Tuning a cascade loop is simple ... Note that we still only have one control valve. Instead of manipulating steam valve directly for temperature control, the valve is now controlling the flow of the ...

Sometimes it makes sense to spring for a feedforward approach This column is moderated by Béla Lipták, automation and safety consultant and editor of the Instrument and Automation Engineers' Handbook ...

If, in addition to the main process variable, additional system variables are measured and given back as secondary process variables, generating subordinate control loops, a cascade ... Steam pressure ...

Abstract: This paper deals with design and implementation of control system for superheated steam temperature control of high pressure ... The designed control algorithm represents standard cascade ...
