Good Tuning: A Pocket Guide

Every practicing instrument, process control and process engineer will want to have this practical and to-the-point pocket guide on good tuning. Good Tuning, A Pocket Guide, Fourth Edition is a portable, concise summary of all the practical considerations for tuning loops. It includes step-by-step descriptions of the three best field-proven tuning procedures, a table of typical tuning settings, a summary of valve performance problems, logic diagrams for trouble-shooting, and more than 70 "rule of thumb." The PID controller has an incredible number of options and parameters besides tuning settings. Most of the power of the PID remains untapped. This fourth edition provides the means to address difficult situations, meet different objectives, deal with a window of allowable controller gains, achieve more robustness, and the basis to get the most out of today's more powerful software tools for auto-tuning and adaptive control. The understanding of the interrelationship between the process, tuning, performance, and PID features enables automation and process engineers to work together to improve process efficiency and capacity.
