Le volume XVI traite de l'électronique de réglage et de commande. Il fait suite au volume XV qui est consacré à l'électronique de puissance. Dans le domaine de l'électronique de réglage et de commande, le problème consiste à construire et appli- quer des dispositifs permettant le traitement de signaux analogiques et logiques. Les puissances en jeu sont en général faibles. Ces dispositifs sont destinés, dans la plupart des cas d'application, à commander des convertisseurs statiques, décrits dans le volu- me XV. Pour la réalisation des dispositifs de réglage et de commande, on utilise des mo- dules analogiques, décrits dans le volume VII, et des modules logiques, décrits dans le volume V. L'assemblage de ces éléments en des montages concrets est le résultat de longs développements et recherches dans l'industrie. Ces dispositifs doivent s'intégrer dans des systèmes complets. Le but de ce volume du Traité d'Electricité est la présen- tation, la description et l'analyse des dispositifs les plus importants utilisés dans le domaine des réglages industriels, ainsi que la description de quelques cas d'application. On peut distinguer trois parties: la première partie (chapitres 1 à 5) est consacrée à la présentation des disposi- tifs; on y travaille au niveau 2 (théorie des circuits) et au niveau 3 (schémas fonctionnels) la deuxième partie (chapitres 6 à 8) traite de l'intégration de ces dispositifs dans des systèmes; on y travaille au niveau 3 (schémas fonctionnels) et 4 (systè- mes, où l'on fait aussi appel à des notions de la théorie du réglage automatique la troisième partie (chapitres 9 à 13) est destinée au traitement plus approfondi d'un domaine d'application, celui des entraînements réglés, où l'on travaille au niveau 3 (schémas fonctionnels) et au niveau 4 (systèmes). L'électronique de réglage et de commande ne s'occupe donc pas seulement des dis- positifs électroniques, mais s'intègre dans un contexte plus large, où l'aspect du système est prédominant. On doit résoudre des problèmes pratiques et théoriques, des problè- mes appartenant au domaine de l'électronique de faible puissance, de l'électronique de puissance, des machines électriques et des installations industrielles.

This dictionary contains 13,000 terms with more than 4,000 cross-references used in the following fields: automation, technology of management and regulation, computing machine and data processing, computer control, automation of industry, laser technology, theory of information and theory of signals, theory of algorithms and programming, philosophical bases of cybernetics, cybernetics and mathematical methods.Automation pertains to the theory, art, or technique of making a machine, a process or a device more fully automatic. Computers and information processing equipment play a large role in the automation of a process because of the inherent ability of a computer to develop decision that will, in effect, control or govern the process from the information received by the computer concerning the status of the process. Thus automation pertains to both the theory, and techniques of using automatic systems in industrial applications and the processes of investigation, design and conversion to automatic methods. Automatic control, automatic materials handling, automatic testing, automatic packaging, for continuous as well as batch processing, are all considered parts of the overall or completely automatic process.The Dictionary consists of two parts, Basic Table and Indexes. In the first part the English terms are listed alphabetically, numbered consecutively and followed by its German, French and Russian equivalents. English synonyms appear as cross-references to the main entries in their proper alphabetical order. The second part of the Dictionary, the Indexes, contains separate alphabetical indexes of the German, French and Russian terms. The reference number(s) with each term stands for the number of the English term(s) in the basic table.Elsevier's Dictionary of Automatic Technics will be a valuable tool for specialists, scientists, students and everyone who takes interest in the problems of investigation devoted to the design, development, and applications of methods and techniques for rendering a process of group of machines self-actuating, self-moving, or self-controlling.

The contemporary industrial robot is the focal point of a wide variety of elements in modern technology. It is a collection of parts, some of which act as drives and some of which act as architectural materials that give the robot body strength. This book is a thorough inventory of the technologies involved and the way in which they meet and work together in order to produce a functional robot arm. The authors have striven to describe thoroughly the components that make up robot arms. This gives both the student and the practitioner a complete view of the principles involved in such components and the differences between existing technologies. However, it is not only the student who benefits from this approach but also the potential robot user who, at the moment, may be faced with a bewildering choice of combinations of different types of components in the robots that are available to him. For example, it is difficult for a production manager to appreciate the differences between robots that use direct current motors, stepping motors and pneumatic actuators. The authors have succeeded in structuring the book so that the reader can weigh up the pros and cons of these different techniques at whatever level of depth he requires. Certainly, the book aims to provide as much depth as there is in these topics without assuming a detailed knowledge of specialized areas of engineering.

An instructive reference that will help control researchers and engineers, interested in a variety of industrial processes, to take advantage of a powerful tuning method for the ever-popular PID control paradigm. This monograph presents explicit PID tuning rules for linear control loops regardless of process complexity. It shows the reader how such loops achieve zero steady-position, velocity, and acceleration errors and are thus able to track fast reference signals. The theoretical development takes place in the frequency domain by introducing a general-transfer-function-known process model and by exploiting the principle of the magnitude optimum criterion. It is paralleled by the presentation of real industrial control loops used in electric motor drives. The application of the proposed tuning rules to a large class of processes shows that irrespective of the complexity of the controlled process the shape of the step and frequency response of the control loop exhibits a specific performance. This specific performance, along with the PID explicit solution, formulates the basis for developing an automatic tuning method for the PID controller parameters which is a problem often met in many industry applications—temperature, pH, and humidity control, ratio control in product blending, and boiler-drum level control, for example. The process of the model is considered unknown and controller parameters are tuned automatically such that the aforementioned performance is achieved. The potential both for the explicit tuning rules and the automatic tuning method is demonstrated using several examples for benchmark process models recurring frequently in many industry applications.

This book concentrates on the problem of accurate modeling of linear systems. It presents a thorough description of a method of modeling a linear dynamic invariant system by its transfer function. The first two chapters provide a general introduction and review for those readers who are unfamiliar with identification theory so that they have a sufficient background knowledge for understanding the methods described later. The main body of the book looks at the basic method used by the authors to estimate the parameter of the transfer function, how it is possible to optimize the excitation signals. Further chapters extend the estimation method proposed. Applications are then discussed and the book concludes with practical guidelines which illustrate the method and offer some rules-of-thumb.
