The vast majority of automatic controllers used to compensate industrial processes are PI or PID type. This book comprehensively compiles, using a unified notation, tuning rules for these controllers proposed from 1935 to 2008. The tuning rules are carefully categorized and application information about each rule is given. The book discusses controller architecture and process modeling issues, as well as the performance and robustness of loops compensated with PI or PID controllers. This unique publication brings together in an easy-to-use format material previously published in a large number of papers and books.This wholly revised third edition extends the presentation of PI and PID controller tuning rules, for single variable processes with time delays, to include additional rules compiled since the second edition was published in 2006.Contents:IntroductionController ArchitectureController Tuning Rules for Self-Regulating Process ModelsController Tuning Rules for Non-Self-Regulating Process ModelsPerformance and Robustness Issues in the Compensation of FOLPD Processes with PI and PID ControllersAppendices:Glossary of Symbols and AbbreviationsSome Further Details on Process ModelingReadership: Control engineering researchers in academia and industry with an interest in PID control and control engineering practitioners using PID controllers. The book also serves as a reference for postgraduate and undergraduate students.
