内容説明

Most books concerning the dynamics of electromechanical power conversion are more or less based on the general approach to such systems, where the problem of electric drives is regarded as rather marginal, in spite of the fact that electric drives in modern industry take up about 80% of the total power used in a given plant. Recently, the field of electric drives has experienced rapid expansion caused mainly by the advances in semiconductors. This book characterizes the present state of knowledge on the dynamics of electric drives. The fundamental problems on the dynamics of electric driving systems, their analysis, synthesis and industrial applications are presented. The method of constructing mathematical models of electromechanical systems is described, based on the Hamilton principle; state variable equations; and the so-called ``independent'' equations. Conversely, the control of such systems is concerned with the problems of optimization, and some of the most commonly used methods of optimization concerning the d.c. and a.c. drives are described. The last chapter discusses some industrial applications of several structures of driving systems.
