This book covers the most important topics that people working as process control engineers and plant operators will encounter. It focuses on PID control, explains when to use P-, PI-, PD- or PID control as well as PID tuning and includes difficult to control process nonlinearities such as valve stiction or sensor problems. The book also explains advanced control strategies that are necessary when single loop control gives insufficient results.

Tore Hägglund received his M.Sc degree in Engineering Physics in 1978 and his Ph.D degree in Automatic Control in 1984, both from Lund Institute of Technology, Lund, Sweden, where he currently is professor. Between 1985 and 1989 he worked for Alfa Laval Automation (now ABB) with development and implementation of industrial adaptive controllers.
Tore Hägglund has written several books, e.g. PID Controllers: Theory, Design, and Tuning (coauthor K. J. Åström), and Process Control in Practice. His current research interests are in the areas of process control, tuning and adaptation, and supervision and detection, with applications mainly in the pulp and paper industry.
