As simple as that – retuning a single oscillatory control loop improved process performance, eliminated unnecessary wear- and-tear, and nearly doubled the associated val ve’s life. Tha t ’s not to mention the benefits of avoiding costly unplanned downtime and not having to assign yet another task to the pl an t ’s maintenance team. The control l o o p’s valve movement measured in terms of Output Travel increased to 110% per hour, and the associated process variability as measured by Average Absolute Error (AAE) stood at 399 pounds per hour. Upon implementing tuning parameters recommended by PlantESP, Output Travel plummeted by 95% to 5% per hour and the AAE value dropped 45% to 218 pounds per hour.
