ac electric motors control advanced design techniques and applications pdf
The last two decades have witnessed spectacular developments in the technologies of power
electronics and microprocessors. Due to these developments, sophisticated power converters
and digital signal processors (DSP) have become available, making possible the use of highperformance AC drives in widespread applications. For this goal to be fully realized, one
should get as much benefit as possible from the considerable progress made in the field of
control theory. Three decades of intensive research activity has resulted in a proliferation of
nonlinear control methods, published in hundreds of journal and conference papers.
not all nonlinear control methods apply to AC motors, but a significant fraction does. The aim of this monograph is to make available to the scientific community a resource reflecting the
wide variety of control problems posed by AC motors and drawing up the state of the art of
the corresponding control methods for design, analysis, and implementation.
In this respect,
special focus is made on the topics of sensorless nonlinear observers, adaptive and robust
nonlinear controllers, output-feedback controllers, fault detection and isolation algorithms,
and fault-tolerant controllers. The most significant developments in these topics, and their
applications to AC motor control, are described in this book, as well as some new research
topics. Most of the concepts and methods are presented by their own inventors.
The book is intended for a wide variety of readers, including academia and industry
researchers, graduate students and their professors, engineers, and practitioners. Although
it includes many aspects of the theory, it is nonetheless beneficial to practitioners who will be
able to use the methods without necessarily understanding every single detail of the theory. It
will also be useful for newcomers to research in the field of AC motor control.
For students and
newcomers, the main prerequisites are undergraduate courses on linear and nonlinear system
control, on electric machines, and on power electronics. Each chapter includes an introduction
and an individual reference list, and the different chapters are written in a way that makes
them readable independently from each other.
