The revised third edition of this best-seller now comes with a “carry-in-the-toolbox” aid designed specifically for those who tune controllers as part of their day-to-day tasks. This compact aid provides easy access to the parameters and calculations needed to tune feedback controllers and covers topics such as improving as-found tuning and making corrections for dead time and non-cascade control. Another valuable tool—Derivation of Equations in Tables 6-8 through 6-12, the bonus material on this page—has also been updated and expanded.

This intermediate-level book explains the application of basic and advanced regulatory control strategies for the wet process industries. Rather than mathematical systems theory, the book builds upon the engineer’s or technician's own experience and knowledge of processes to demonstrate the application of successful control strategies.

Following a summarization of the characteristics of processes and feedback control loops, attention is given to the application of advanced regulatory control (ARC) strategies to provide significant economic benefit. The latter portion of the book gives an overview of the next level of control—advanced process control (APC). New topics include an expanded coverage of set-point weighting controllers, an amplified discussion of valve problems, a control algorithm for dead-time processes, expanded coverage of cross-limiting control systems, and a new heuristic procedure for improving ""as-found"" tuning. End of chapter exercises have been added. Suitable for the beginning or experienced engineer or technician.
