Free training CD

Hubertus,Wis.— A free CD from ExperTune teaches how to diagnose and fix problems on badly performing loops. Roughly 75% of process control loops cause more variability running in automatic mode than in manual. A third of them oscillate because of nonlinearities: hysteresis, stiction, deadband, or nonlinear process gain. Another third oscillate because of poor controller tuning. The remaining loops do so due to poor design. The CD uses a case study to explain and demonstrate the basic steps used to analyze and tune control loops. www.expertune.com Expertune
