In view of the rapid changes in requirements, it has became necessary to place at the reader's disposal a book dealing with basic and advanced concepts and techniques for the monitoring and control of chemical and biochemical processes, as well as with the aspects of the implementation of these different robust techniques. To make the ideas covered in this book accessible to a larger audience, the authors attempted to present a balanced view of the theoretical and practical issues of control systems. Different cases are presented to illustrate the controller and observer design procedures and their dynamic effects in the closed-loop. The book consists of peer-reviewed contributions and aims the integration of recent research by a group of colleagues working on theory and practice of the process control. In order to embrace as chemical as control engineering themes, authors have proposed different kind of processes and distinct control scopes. This book is an effort to incorporate and link both theory-practice and chemical-control engineering.
