Drives And Control For Industrial Automation

Drives and Control for Industrial Automation presents the material necessary for an understanding of servo control in automation. Beginning with a macroscopic view of its subject, treating drives and control as parts of a single system, the book then pursues a detailed discussion of the major components of servo control: sensors, controllers and actuators. Throughout, the mechatronic approach – a synergistic integration of the components – is maintained, in keeping with current practice. The authors’ holistic approach does not preclude the reader from learning in a step-by-step fashion – each chapter contains material that can be studied separately without compromising understanding. Drives are described in several chapters according to the way they are usually classified in industry, each comprised of its actuators and sensors. The controller is discussed alongside. Topics of recent and current interest – piezoelectricity, digital communications and future trends – are detailed in their own chapters.

Provides broad insights into problems of coding control algorithms on a DSP platform. - Includes a set of Simulink simulation files (source codes) which permits readers to envisage the effects of control solutions on the overall motion control system. -bridges the gap between control analysis and industrial practice.

Electrical drives convert electrical energy into mechanical energy and act as a intermediary between electrical supply systems, various energy sources, driven machines and the energy consumer. Electrical drives are major component in industrial applications, driven technical developments and focus of various developments. The core component of every electrical drive is the motor. This book is divided into six modules. Module 1 deals with DC machines, principles of operation, emf equation and armature reaction. Module 2 contain principles of DC motors and their torque-speed characteristics. Module 3 mainly deals with transformers and their efficiency calculations. In module 4, various aspects of induction motors were covered. Module 5 and 6 mainly focusses on split phase and stepper motors. Today electrical drives and their automation has become an essential integral part of every system and process. This book will focus primarily on electrical drives and their control for automation, although some of the topics covered will remain applicable to process control.

Electrical drives play an important part as electromechanical energy converters in transportation, materials handling and most production processes. This book presents a unified treatment of complete electrical drive systems, including the mechanical parts, electrical machines, and power converters and control. Since it was first published in 1985 the book has found its way onto many desks in industry and universities all over the world. For the second edition the text has been thoroughly revised and updated, with the aim of offering the reader a general view of the field of controlled electrial drives, which are maintaining and extending their importance as the most flexible source of controlled mechanical energy.

The authors and editors of this Handbook have attempted to fill a serious gap in the professional literature on industrial automation. Much past attention has been directed to the general concepts and philosophy of automation as a way to convince owners and managers of manufacturing facilities that automation is indeed one of the few avenues available to increase productivity and improve competitive position. Seventy-three contributors share their knowledge in this Handbook. Less attention has been given to the "What" and "How" of automation. To the extent feasible and practical within the confines of the pages allowed, this Handbook concentrates on the implementation of automation. Once the "Go" signal has been given by management, concrete details-not broad definitions and philosophical discussions-are required. To be found in this distinctly different book in the field are detailed parameters for designing and specifying equipment, the options available with an evaluation of their relative advantages and limitations, and insights for engineers and production managers on the operation and capabilities of present-generation automation system components, subsystems, and total systems. In a number of instances, the logical extension of current technology into the future is given. A total of 445 diagrams and photos and 57 tables augments detailed discussions. In addition to its use as a ready reference for technical and management personnel, the book has wide potential for training and group discussions at the college and university level and for special education programs as may be provided by consultants or by "in-house" training personnel.

Electrical drives play an important role as electromechanical energy converters in transportation and most production processes. The ease of controlling electri cal drives is an important aspect for meeting the increasing demands by the user with respect to flexibility and precision, caused by technological progress in industry. Conversely, the control of electrical drives has in the past provided strong in centives to control engineering in general, leading to the development of new other areas of control. This is due to control structures and their introduction to stringent operating conditions and widely varying specifications - a drive may alternately require control of torque, acceleration, speed or position - and the fact that most electric drives have - in contrast to chemical or thermal pro cesses - well defined structures and consistent dynamic characteristics. During the last few years the field of controlled electrical drives has experi enced rapid expansion caused mainly by the advances of semiconductors in the form of power electronics as well as analogue and digital signal electronics, eventually culminating in microelectronics and microprocessors. The in troduction of electronically switched solid-state power converters has renewed the search for ac motor drives, not subject to the limitations of the mechanical commutator of de drives; this has created new and difficult control problems.

In 1965-66 the authors have given courses for AEG engineers in the area of "Industrial Installations". The purpose of the courses was to enable the parti cipants to carry out calculations on feedback control for drive systems. In 1967 these courses were printed under the title "Calculation of Feedback Control Circuits for Drive Systems". This handbook with the same title arises out of the revision of that publication. The scope was extended by the addition of new sections. Today, many specialized books and publications in the area of control technology are available to the reader. Most of them are characterized by a presentation of the mathematical theory of the fundamental concept and pro cedures involved. However, there are few instruction books containing worked examples on the practical application of those procedures. This book is intended to introduce the reader to the practical calculation of feed back control circuits without too much theory. Electric drives were chosen as the area of application. In an instruction book with examples of application, the problem arises of reducing the theoretical treatment of fundamentals and the mathematical deriva tions without gaps arising and without the necessity for consulting additional works of reference. The chosen way may be briefly explained.

The purpose of this book is to familiarize the reader with all aspects of electrical drives. It contains a comprehensive user-friendly introductory text.
