The idea of writing this book arose from the need to investigate the main principles of
modern power electronic control strategies, using fuzzy logic and neural networks, for
research and teaching. Primarily, the book aims to be a quick learning guide for
postgraduate/undergraduate students or design engineers interested in learning the
fundamentals of modern control of drives and power systems in conjunction with the
powerful design methodology based on VHDL.
At the same time, the book is structured to address the more complex needs of
professional designers, using VHDL for neural and fuzzy logic systems design, by
including comprehensive design examples. This facilitates the understanding of hardware
description language applications and provides a practical approach to the development
of advanced controllers for power electronics.
The first section of the book contains a brief review of control strategies for electric
drives/power systems and a summary description of neural networks, fuzzy logic, electronic
design automation (EDA) techniques, ASICs/FPGAs and VHDL. The aspects covered
allow a basic understanding of the main principles of modern control. The second
section contains two comprehensive case studies. The first deals with neural current and
speed control of induction motor drives, whereas the second presents the environmentally
friendly fuzzy logic control of a diesel-driven stand-alone synchronous generator set.
Both control strategies were implemented in Xilinx FPGAs and comprehensively tested
by simulation and experimental measurements.
This book brings together the complex features of control strategies, EDA, neural
networks, fuzzy logic, electric machines and drives, power systems and VHDL and
forms a basic guide for the understanding of the fundamental principles of modern
power electronic control systems design. To be expert in the design of advanced digital
controllers for drives and power systems, extra reading is strongly recommended and
comprehensive material is referenced in the bibliographical section. The book includes
a number of recent research results from work carried out by the authors, who are
members of the electronic control and drives research group at De Montfort University,
