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.

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.

This book reflects the considerable current industrial interest and investment in process control systems. The use of computer systems in process control can provide great benefits, and it is estimated that efficiency can be increased by up to 30%. It is not surprising, therefore, that there have been considerable efforts by system designers and users to introduce and use such systems. Process hardware is integrated into a complete production system through data processing. It is for this purpose that technical specialists (e. g. electrical, mechanical, electronics, communication and process engineers and program mers) are involved in data processing. The scope of this book is therefore to assist in the selection of computer hardware and software that match the functional specification of the data processing component of a particular system. The principal points covered in this book are set out below. Part One: Production process hardware for a standard process is outlined and the information processing hardware is described. Large mechanical process hardware and process information devices (e. g. sensors and control elements involved in the process) create a coherent production unit, or system, which can be the control unit (i. e. the basic process unit). The hardware processes are described and the mathematics explained. This enables the application of control laws in order to linearize the process about its working point, as well as a stratification of process control tasks.
