Klappentext zu „Advanced Practical Process Control “
In the process industries there is an ongoing need for improvement of the opera tion of the process. One of the disciplines that will help the process engineer to achieve this is process control. There are many industrial automation systems to day that will offer powerful tools to meet the process control needs of industries with continuous, batch and discrete operations. Advanced control solutions sustain and improve the plant's competitiveness by ensuring: - safe operations - compliance with environmental regulations - effective use ofraw materials and energy - efficient production - manufacturing ofhigh quality products - flexible accommodation ofchanging process requirements This book was written from the perspective of introducing advanced control con cepts, which can help the engineer to reach the aforementioned goals. Many ad vanced control techniques have been implemented in industry in recent years, since hardware and software platforms are becoming increasingly powerful. Manufacturers ofprocess control equipment call this hardware and software envi ronment generally 'distributed control system'. The distributed control system equipment offers the engineer an excellent plat form for writing and implementing advanced control solutions. However, most large chemical and petrochemical manufacturers hire control specialists to imple ment these control solutions, while small manufacturers often lack the funds to hire these professionals. Therefore it is our experience that in the latter case, proc ess engineers often write the control programs required to improve process opera tion.

Pressezitat
From the reviews:"The book Advanced Practical Process Control by Roffel and Betlem complements the textbook literature in the field of process control with a solution oriented approach. ... The approach is very practical and solution oriented. It aims at familiarizing the reader with essential concepts of advanced process control as they are employed nowadays in the process industries. ... the book definitely does enrich the textbook literature on process control. ... The target audience is indeed the industrial practitioner or the chemical engineering student ... ." (W. Marquardt, International Journal of Robust and Nonlinear Control, Vol. 16 (2), 2006)
"This book is to help the process engineer to start from the available theory and to build control solutions. ... Having some theoretical background in process dynamics, identification and optimal control, this book ... will help the process engineer to solve control problems for process improvement tasks in practice." (Kurt Marti, Zentralblatt MATH, Vol. 1042 (17), 2004)"The book Advanced Practical Process Control ... has been written for senior and graduate students as a comprehensive textbook on advanced process control with a solution-oriented approach. ... The book covers a large array of process-control solutions. ... The book is extremely well organized. Each chapter ... gives a clear summary of what is to be described. ... illustrated by numerous pictures, plots, and flow diagrams. ... The presentations are clear, and the concepts and ideas are illustrated extremely well through numerous, interesting examples."
