Practical Process Control: Tuning and Troubleshooting

December, 2009
Practical Process Control (loop tuning and troubleshooting). This book differs from others on the market in several respects. First, the presentation is totally in the time domain (the word "LaPlace" is nowhere to be found). The focus of the book is actually troubleshooting, not tuning. If a...

Process Automation Corner
Terry McMahon
Seven years ago, I wrote a column for another publica­ tion entitled “The U.S. Chemical Industry: R.I.P.” This pillar of American economic strength, which a few years earlier was the leading exporter among U.S. manufac­turing sectors (with net exports of $15–20 billion annually), was shriveling due in large part to policy blunders and regula­tory mistakes.
