Process Dynamics and Control

This book is an introductory course that provides an appropriate balance between process control theory and practice. In particular it emphasizes on dynamic behavior, physical and empirical modeling, computer simulation, measurement and control technology, basic control concepts, and advanced control strategies. The mathematical level of the book is oriented toward a junior or senior student who has taken at least one course in differential equations. Additional mathematical tools required for the analysis of control systems are introduced along the book as needed. The book emphasizes process control techniques that are used in practice and provides detailed mathematical analysis only when it is essential for understanding the material. Key theoretical concepts are illustrated with examples. The book is divided in four parts. Part I (chapters 1 to 2) provides an introduction to process control and an in-depth discussion on process modeling. The development of dynamic models for representative processes, like a stirred-tank blending system are used as illustrative examples throughout the book. Part II (chapters 3 to 7) is concerned with the analysis of the dynamic behavior of processes. A key issue is the determination of the transient response that occurs after a process disturbance occur, a grade change is initiated, or a process is started up or shut-down. Important analysis toll are introduced, the Laplace transform and the transfer function. For many practical control applications, it is not feasible to develop a physically based, dynamic model. For this the important topic of empirical models and their development from plant and process data are presented. Both continuous-time and discrete-time models are considered here. Part III (chapters 8 to 15) addresses the fundamental concepts of feedback and feedforward control. The topics included the PID controller and an overview of the process instrumentation and control hardware and software that are necessary to implement process control, The important relationship between process design and process control is emphasized, and a whole section is dedicated to process safety. The design and analysis of feedback control systems, as well as new methods for controller design, tuning, and troubleshooting receive considerable attention. This part concludes with a chapter on feedforward and ratio control. Part IV (chapters 16 to 24) is concerned with advanced process control techniques. The topics include digital control, multivariable control and enhancements of PID control, such as cascade control, selective control, and gain scheduling. Powerful techniques like real time optimization and model predictive control (MPC) that have had significant impact on industrial practice are covered on dedicated and separated chapters. Also process monitoring, batch processes control, and plant-wide control are also developed on individual chapters. Illustrative case studies are included in this part of th

I have just finished a postgraduate course in process dynamics based on this book. I have a maths background so I found some of the concepts hard going at the start of the course. I have used this book costantly throughout the course and I have found it to be excellent. It has really helped my understanding of the subject, so much so that I want to write my Master`s thesis in process engineering and process dynamics. I have enjoyed everything about the course and it is all because of this book.

Process dynamics and control is a vast subject, profoundly important for maximizing value in plant operations, but unfortunately often neglected by undergraduate students. This book by three of the most illustrious professors of chemical engineering distills their expertise and wisdom, as teachers with about 100 years combined teaching experience, into a highly accessible and cogent textbook. The book contains excellent discussions and expositions of just about all the technical concepts one would ever need in industrial practice. The example problems are juicy, to say the least, and complement the text very nicely. Those who know how to use Matlab or Mathematica will benefit hugely from solving the computer problems. In my opinion, this book should be a required text for all undergraduate chemical engineering programs, along with the book by Prof. Harmon Ray and B. Ogunnaike (Oxford).

Four years of chemical engineering education and finally, a book worth remembering. Seborg leaves nothing out. From the simplest principles to the weirdest homework problems, the book does a great job of TEACHING, not just INFORMING. As a reference, it might not be too great, but for pure teaching effect, this is the absolute best choice.

This book shows how to think and approach and find out the way to solve your problems in the process control field. It contains a lot of examples of actual process properties,dynamics and simulation models, and control problems. And there is a introduction to the advanced control systems.
