ExperTune, Inc.rming process control loops reduce plant profitability. This free CD teaches how to diagnose and fix the problems on your ExperTune, Inc.rming loops. Roughly 75% of process control loops cause more variability running in automatic mode than in manual. A third of them oscillate because of non-linearities: hysteresis, stiction, dead band, and non-linear process gain. Another third oscillate because of poor controller tuning, and the remaining loops due too poor design. When a control loop is running optimally, variability is minimized. The plant can operate closer to specifications, maximizing production and profitability.
The CD uses a case study of a typical loop. It explains and demonstrates the basic steps to analyze and tune the control loop.
