Control Loop Foundation Reprint

Manual Tuning Integrating Process

A book goes through many reviews and edits before it can be published. Still, it is very difficult for the authors and reviewers to catch all the typo’s in the original text and those that are introduced during the type setting process (formatting for publication). ISA recently notified me that the book that Mark Nixon …
