PID Control Loop/Valve Tuning using model-based methods. Identification of valves with mechanical issues such as hysteresis and stiction. The average reduction in process variability is 47.6% for 36 ethanol plants (1,462 loops/valves tuned). Advanced Control strategies specific to Ethanol Plants in the DCS. This includes Advanced Fermentation Temperature Control, Predictive, and Constraint Dryer/TO Temperature Control (Energy Center), and Front End Density, Ferm Gap Control and Water Balance. All done in the DCS (no external software, PC's or annual maintenance fees).
