Synopsis
Mastering the synergy of electromagnetics, control, power electronics and mechanical concepts remains a intellectual challenge. Nevertheless this barrier must be overcome by engineers and senior students who have a need or desire to comprehend the theoretical and practical aspects of modern electrical drives. In this context the term 'drive' represents a plethora of motion systems as present in industry. The text "Advanced Electrical Drives", volumes I and II builds on basic concepts outlined in our book "Fundamentals of Electrical Drives" hence it is prudent for the uninitiated reader to consider this material prior to tackling the more advanced material presented in this text. Others well versed in the basic concepts of electrical drives should be able to readily assimilate the material presented as every effort has been made to ensure that the material presented can be mastered without the need to continually switch between the three books. In our previous work the unique concept of an Ideal Rotating Transformer (IRTF) as developed by the authors was introduced to facilitate the basic understanding of torque production in electrical machines. The application of the IRTF module to modern electrical machines as introduced in "Fundamentals of Electrical Drives" is fully explored in volume I and as such allow the user to examine a range of unique dynamic and steady-state machine models which covers brushed DC, non-salient/salient synchronous and induction machines. In addition, volume I explains the 'universal field oriented' (UFO) concept which demonstrates the concepts of modern vector control and exemplifies the seamless transition between so called 'stator flux' and 'rotor flux' oriented control techniques. This powerful tool is used for the development of flux-oriented machine models of rotating field machines. These models form the basis of UFO vector control techniques which are covered extensively together with traditional drive concepts. In the sequel of Volume I attention is given to the dynamic modelling of 'Switched Reluctance' (SR) drives, where a comprehensive set of modeling tools and control techniques are presented which are complemented by a set of 'build and play' modules. Volume II builds on the material presented inVolume I and considers among others 'skin-effect'and 'single-phase' operation of induction machines. In addition, attention is given to 'Direct Torque Control'(DTC), and sensorless drive operation. As with the previous book the inter active learning process using 'build and play' modules is continued. Again the simulation tool 'Caspoc' is used which contains a tailored set of modules which bring to life the circuit and generic models introduced in the text. This approach provides the reader with the opportunity to interactively explore and fully comprehend and visualize the concepts presented in this text. For this purpose a CD is provided with realtime modules which allows the reader to view the simulations without further software licensing needs.

Review
From the reviews:
"This book on fundamentals of electrical drives provides the background of modern electrical drives. ... The uniqueness of this book is that the authors use generic models to represent drive components. ... This would be a great book for electrical engineers learning about electric drives and could also be used for a course in electrical drives ... ." (Electrical Insulation Magazine, Vol. 24 (5), September/October, 2008)

This book helps students and engineers appreciate and understand the fundamental concepts of the modern electrical drives used in thousands of applications, from robotics and household appliances to wind turbines and hybrid vehicles. Updates to this second edition cover innovations in machine design, power semi-conductors, digital signal processors and simulation software. An interactive learning approach is taken in this text: theory and calculations are augmented by generic models which are transposed to a simulation platform. This 'build and play' method visualizes the dynamic operation of a comprehensive set of modules ranging from an inductance to a novel 'ideal rotating transformer' (IRTF). This module is at the center of the generic models used to explore the dynamic and steady state operation of grid and converter fed induction, synchronous and DC machines. The section on modulation and control emphasizes the role of power electronics and digital signal processors in drives. All figures in this text are included in the downloadable files in order to help with the preparation of customized Power Point type lecture material. Fundamentals of Electrical Drives is perfect for readers with basic engineering knowledge who have a need or desire to comprehend and apply the theory and simulation methods utilized by drive specialists throughout the world.
