Discusses the most important and industrially advanced control technology of AC machines in one single volume This book provides an initial guideline to students and professionals. It focuses on the advanced control of AC machines and will keep the readers abreast with the latest technology. The special features of the book are exhaustive simulation models based on Matlab/Simulink. Matlab/Simulink is nowadays the integral part of the taught courses at undergraduate and postgraduate programme and also extensively used in industries. Thus the simulation models will provide a handy tool to students, practising engineers and researchers, to verify the algorithms, techniques and models. Once familiar with the models presented in the book the students and practising engineers can develop and verify their own algorithms and techniques. Integrates a diverse range of topics into one volume, including all the latest developments and unique author research Covers advanced concepts of AC motor drives systematically for thorough understanding and discusses the modelling, analysis and control of multi-phase induction motor drives Model predictive control applied to power converters and AC drives are illustrated together with their simulation models Matlab/Simulink diagrams enable the reader to run the simulations Includes end-of-chapter questions for students and answers available on a complementary website, along with Power Point slides
