Techniques such as dead time compensation, adaptive control and Kalman filtering have been around for some time, but as yet find little application in industry. This is due to several reasons, including: Articles in the literature usually assume that the reader is familiar with a specific topic and are therefore often difficult for the practicing control engineer to comprehend. Many practicing control engineers in the process industry have a chemical engineering background and did not receive a control engineering education. There is a wide gap between theory and practical implementation, since implementation is primarily concerned with robustness, and theory is not. The user therefore has to build an "expert shell" in order to achieve the desired robustness. Little is published on this issue, however. This book tries to promote the use of advanced control techniques by taking the reader from basic theory to practical implementation. It is therefore of interest to practicing control engineers in various types of industries, especially the process industry. Graduate and undergraduate students in control engineering will also find the book extremely useful since many practical details are given which are usually omitted in books on control engineering. Of special interest are the simulation examples, illustrating the application of various control techniques. The examples are available on a 5-1/4" floppy disk and can be used by anyone who has access to LOTUS 1-2-3. Chapter 1 is the introduction; Chapters 2 through 6 deal with distributed control system networks, computer system software, computer system selection, reliability and security, and batch and continuous control. Chapter 7 gives and introduction to advanced control. Chapters 8 through 11 deal with dead time compensation techniques and model identification. Chapters 12 through 14 discuss constraint control and design, and the adjustment and application of simple process models and optimization. Chapter 15 gives a thorough introduction to adaptive control, and the last two chapters deal with state and parameter estimation. This book is a valuable tool for everyone who realizes the importance of advanced control in achieving improved plant performance. It will take the reader from theory to practical implementation.

Offering a modern, process-oriented approach emphasizing process control scheme development instead of extended coverage of LaPlace space descriptions of process dynamics, this text focuses on aspects that are most important for process engineering in the 21st century. Instead of starting with the controller, the book starts with the process and moves on to how basic regulatory control schemes can be designed to achieve the process’ objectives while maintaining stable operations. In addition to continuous control concepts, process and control system dynamics are embedded into the text with each new concept presented. The book also includes sections on batch and semi-batch processes and safety automation within each concept area. It discusses the four most common process control loops—feedback, feedforward, ratio, and cascade—and discusses application of these techniques for process control schemes for the most common types of unit operations. It also discusses more advanced and less commonly used regulatory control options such as override, allocation, and split range controllers, includes an introduction to higher level automation functions, and provides guidance for ways to increase the overall safety, stability, and efficiency for many process applications. It introduces the theory behind the most common types of controllers used in the process industries and also provides various additional plant automation-related subjects.

Introduction to Process Control, Second Edition provides a bridge between the traditional view of process control and the current, expanded role by blending conventional topics with a broader perspective of more integrated process operation, control, and information systems. Updating and expanding the content of its predecessor, this second edition addresses issues in today’s teaching of process control. Teaching & Learning Principles Presents a concept first followed by an example, allowing students to grasp theoretical concepts in a practical manner Uses the same problem in each chapter, culminating in a complete control design strategy Includes 50 percent more exercises Content Defines the traditional and expanded roles of process control in modern manufacturing Introduces the link between process optimization and process control (optimizing control), including the effect of disturbances on the optimal plant operation, the concepts of steady-state and dynamic backoff as ways to quantify the economic benefits of control, and how to determine an optimal transition policy during a planned production change Incorporates an introduction to the modern architectures of industrial computer control systems with real case studies and applications to pilot-scale operations Discusses the expanded role of process control in modern manufacturing, including model-centric technologies and integrated control systems Integrates data processing/reconciliation and intelligent monitoring in the overall control system architecture Web Resource The book’s website offers a user-friendly software environment for interactively studying the examples in the text. The site contains the MATLAB® toolboxes for process control education as well as the main simulation examples from the book. Access the site through the authors’ websites at www.pseonline.net and www.chms.ucdavis.edu/research/web/pse/ahmet/ Drawing on the authors’ combined 50 years of teaching experiences, this classroom-tested text is designed for chemical engineering students but is also suitable for industrial practitioners who need to understand key concepts of process control and how to implement them. The authors help readers see how traditional process control has evolved into an integrated operational environment used to run modern manufacturing facilities.

Please note this is a Short Discount publication. Process planning involves creating detailed plans of the manufacturing steps and equipment necessary to produce a finished part. Using the variant method, CAPP groups families of parts by a structured classification and coding plan. This report summarizes the state–of–the–art and future trends in the area of CAPP. The computer is a vital part of the process planning function, which includes two different approaches. One is called the variant (similar part) method of process planning and the other is generative (expert system–based). Both will produce similar process plans. Most computer applications, however, are of the variant type, because the software is easier to develop and new process plans are based on previous ones.
