Introduction To Process Control

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.
