Course description
Practical PID Control and Loop Tuning - IC-74
This workshop provides instrumentation, automation, and process engineers and technicians with the basic theoretical and practical understanding of regulatory control systems and how this can be applied to optimize process control in terms of quality, safety, flexibility, and costs. Centered on the ISA-recommended PC-Control LAB simulator, participants will learn through active participation using exercises, questionnaires, and a series of 16 practical simulation sessions covering: process reaction; tuning methods; diagnostic tools; effect of different algorithms; surge tank level control; analysis of such problems as valve hysteresis, stiction and non-linearities and the impact on controllability; and integral windup.
"Learning about the practical applications of PID control. We were provided many examples." - Facilities I&E Engineer, United States
"I enjoyed seeing concepts applied in industry relevant settings." - Engineer
