Dynamics is a science concerned with movement and changes. In
the most general approach it relates to life processes as well as
behavior in nature in rest. It governs small particles, technical
objects, conversion of matter and materials but also concerns
people, groups of people in their individual and, in particular,
social dimension.
In dynamics we always have to do with causes or stimuli for
motion, the rules of reaction or behavior and its result in the
form of trajectory of changes.
This book is devoted to dynamics of a wide class of specific but
very important objects such as electromechanical systems. This is a
very rigorous discipline and has a long tradition, as its
theoretical bases were formulated in the first half of the XIX
century by d' Alembert, Lagrange, Hamilton, Maxwell and other
prominent scientists, but their crucial results were based on
previous pioneering research of others such as Copernicus, Galileo,
Newton...
This book in its theoretical foundations is based on the
principle of least action which governs classical as well as
relativistic mechanics and electromagnetism and leads to Lagrange's
equations which are applied in the book as universal method to
construct equations of motion of electromechanical systems. It
gives common and coherent grounds to formulate mathematical models
for all lumped parameters' electromechanical systems, which are
vital in our contemporary industry and civilized everyday life.
From these remarks it seems that the book is general and
theoretical but in fact it is a very practical one concerning
modern electrical drives in a broad sense, including
electromechanical energy conversion, induction motor drives,
brushless DC drives with a permanent magnet excitation and switched
reluctance machines (SRM). And of course their control, which means
shaping of their trajectories of motion using modern tools, their
designed autonomy in keeping a track according to our programmed
expectations.
The problems presented in the book are widely illustrated by
characteristics, trajectories, dynamic courses all computed by use
of developed simulation models throughout the book. There are some
classical subjects and the history of the discipline is discussed
but finally all modern tools and means are presented and
applied.
More detailed descriptions follow in abstracts for the
particular chapters.
The author hopes kind readers will enjoy and profit from reading
this book.
