ExperTune optimizes loop performance

By Control Engineering Staff October 1, 2000

Hubertus, Wis. -Loops tuned for setpoint changes often perform poorly during process disturbances and loops tuned for process disturbances are likely too agressive during a setpoint change. ExperTune’s new software optimizes loop performance for both scenarios by combining a setpoint filter with optimal steady state tuning ensuring the loop reacts equally well to plant startups, product switchovers, and steady state operations. Using ExperTune’s simulation capability, users can view the effects of the tuning parameters and setpoint filter off-line before applying it to real process loops. When satisfied with the performance, ExperTune creates a report of the entire loop optimization, including all the anaylsis graphs, performance indices, loop diagnosis, and the setpoint filter in a Microsoft Word document.
