Design of Control Systems for DC Drives

This book is intended to introduce the reader to the practical calculation of feedback control circuits by examples of application. The material is presented in the order of the work necessary in the practical investigation of feedback control systems: analysis of the technical construction, setting up the equations, transformation into frequency notation, normalization, drawing of the system diagram and the Bode diagram, determination of the control system parameters and the behaviour in real time. Only an understanding of basic mathematics and of basic electricity is prerequisite. The book can be used for independent study, to serve the specialist as a reference book, and to offer the drive-system engineer a comprehensive presentation of the standard problems and solutions of drive-systems engineering. Although for the most part examples of drive systems will be used, the contents is presented in such an easy way that it can also be read by other than drive-system engineers.

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."
