Microcomputer Application In Process Control

This symposium brings together the research from different disciplines of process control, and discusses the problems encountered in the application of automation systems. The papers in this volume analyze the results of theoretical research and how far applications have been developed, new design methodologies and technologies, to give a comprehensive overview of the state of the art of this fast-developing science.

Microcomputers for Process Control provides an introduction to microprocessor technology for process monitoring and control. The book begins with an overview of microprocessor applications in areas such as consumer products, factories, and telecommunications. This is followed by separate chapters that discuss microcomputer technology; electrical interface to enable plant monitoring and control by microcomputer; microcomputer system hardware and software; VDU-based plant monitoring systems; and methods of computer control. This book is aimed at practicing engineers in industry who wish to acquire a base of understanding of this technology and also to learn how microcomputers can actually be applied in real plant situations. Considerable emphasis is given to plant measurements, interfacing techniques and applications of microcomputers for plant monitoring and control. No prior knowledge of microprocessor technology is assumed, but some awareness of plant measurement and control problems will assist the reader. Students undertaking engineering courses which include microelectronics or process control studies should also find the text helpful.

The introduction of the microprocessor in computer and system engineering has motivated the development of many new concepts and has simplified the design of many modern industrial systems. During the first decade of their life. microprocessors have shown a tremendous evolution in all possible directions (technology. power. functionality. I/O handling. etc). Of course putting the microprocessors and their environmental devices into properly operating systems is a complex and difficult task requiring high skills for melding and integrating hardware. and systemic components. software This book was motivated by the editors' feeling that a cohesive reference is needed providing a good coverage of modern industrial applications of microprocessor-based real time control, together with latest advanced methodological issues. Unavoidably a single volume cannot be exhaustive. but the present book contains a sufficient number of important real-time applications. The book is divided in two sections. Section I deals with general hardware. software and systemic topics. and involves six chapters. Chapter 1. by Gupta and Toong. presents an overview of the development of microprocessors during their first twelve years of existence. Chapter 2. by Dasgupta. deals with a number of system software concepts for real time microprocessor-based systems (task scheduling. memory management. input-output aspects. programming language reqUirements.

Considers the application of modern control engineering on digital computers with a view to improving productivity and product quality, easing supervision of industrial processes and reducing energy consumption and pollution. The topics covered may be divided into two main subject areas: (1) applications of digital control - in the chemical and oil industries, in water turbines, energy and power systems, robotics and manufacturing, cement, metallurgical processes, traffic control, heating and cooling; (2) systems theoretical aspects of digital control - adaptive systems, control aspects, multivariable systems, optimization and reliability, modelling and identification, real-time software and languages, distributed systems and data networks. Contains 84 papers.

Digital Computer Applications to Process Control presents the developments in the application of digital computers to the control of technical processes. This book discusses the control principles and includes as well direct feedback and feed forward control as monitoring and optimization of technical processes. Organized into five parts encompassing 77 chapters, this book begins with an overview of the two categories of microprocessor systems. This text then discusses the concept of a sensor controlled robot that adapts to any task, assures product quality, and eliminates machine tending labor. Other chapters consider the ergonomic adaptation of the human operator's working conditions to his abilities. This book discusses as well the self-tuning regulator for liquid level in the acetic acid evaporator and its actual performance in production. The final chapter deals with algebraic method for deadbeat control of multivariable linear time-invariant continuous systems. This book is a valuable resource for electrical and control engineers.
