Continuous Process: Tuning Loops

SKU: ACPTL00CENDuration: 120 Minutes

This course is designed to familiarize participants with the basic principles of tuning control loops. After completing this course, participants should be able to describe how to prepare for tuning a loop and how to tune a loop manually using a systematic trial and error method, the Ziegler-Nichols open loop method, and the Ziegler-Nichols closed loop method. They should also be able to describe how tuning can be accomplished by the auto-tune function, by artificial intelligence features, and by tuning software.
