Proper tuning of PID loops can have a great deal of impact on the throughput, yield, and efficiency of your process. This presentation will explain proper techniques for tuning various types of PID loops, as well as the impact on your process of improperly tuned loops. 1) What is a PID loop—Simple discussion of the components of a PID loop and how they apply to the overall control process. Detailed but simple explanation of how each term of a loop affects the operation of a PID loop. 2) Process reaction—Discussion of how a process will react to a properly and an improperly tuned loop. 3) Tuning—Basic step-by-step approach to achieving optimal tuning results. 4) Dynamic parameters—Why the dynamic substitution of tuning parameters may be required to provide optimal results in various processes.
