This book is supported by theories, experiments, and simulation examples for each technique covered. Topics explored in this book include: Electrical and mechanical parameter estimation techniques, including those based on current/voltage injection and position offset injection, under constant or variable speed and load for sensored or sensorless controlled PMSMs, accounting for magnetic saturation, cross-coupling, inverter nonlinearity, temperature effects, and moreRecursive least squares, the Kalman filter, model reference adaptive systems, Adaline neural networks, gradient-based methods, particle swarm optimization, and genetic algorithmsApplications of parameter estimation techniques for improvement of control performance, sensorless control, thermal condition monitoring, and fault diagnosisThis book is an essential reference for professionals working on the control and design of electrical machines, researchers studying electric vehicles, wind power generators, aerospace, industrial drives, automation systems, robots, and domestic appliances, as well as advanced undergraduate and graduate students in related programs of study.

The electrification of the economy entails the development and optimization of efficient electrical machines. Permanent magnet machines use permanent magnets, rather than windings, for field excitation. They are more efficient than other electrical machine technologies for high-efficiency applications. Multiphase machines, as compared to 3-phase machines, have advantages including lower torque pulsation, higher power density, and better fault tolerance.This book offers concise and systematic coverage of multiphase permanent magnet machines and control techniques. It gives an overview of multiphase machines and control techniques in the context of various electrical machine technologies and presents the advantages of multiphase electrical machines. Applications are covered, including wind turbine generators, electric vehicles, electric ships, and aircraft and train propulsion. Machine topologies, modelling, design, control, pulse-width modulation, fault-tolerance, and reduction of current harmonics and torque ripples are considered.Multiphase Permanent Magnet Synchronous Machines and Drives: Principles, design, and control is written for industrial engineers and researchers, including PhD and post-doctoral research students working on electrical machines and drives, as well as for researchers working on electric vehicles, wind power generators, aerospace, electric ships and trains. Following a general introduction, chapters cover winding configurations, multiphase and dual-three-phase permanent magnet synchronous machines (PMSMs), modelling, design, modulation strategies, field-oriented control, direct torque control, model reference control, sensorless control, and also fault tolerant control for multiphase PMSMs. The logical progression from fundamental concepts to state-of-the-art research outcomes helps readers understand and use multiphase electrical machines.

This textbook is a comprehensive review of many different areas in solar-pumped lasers design and characterization. It enables readers to develop their skills in general solid-state laser design and solar collector design and provides numerous solved exercises at the end of each chapter to further this development. This book begins by introducing the brief history of solar-pumped laser and its potential applications. It explains the basic theories of imaging and non-imaging primary, secondary, and tertiary solar concentrators. It discusses solar-pumped solid-state laser theory and solar-to-laser power conversion efficiencies. There are chapters dedicated to ZEMAX and LASCAD numerical simulation tools, to help develop readers’ skills in innovative solid-state laser design. This book is one of the first books to relate concentrated solar energy technologies to solid-state laser technologies and is therefore of interest to students, academics, engineers, and laser and optical system designers.
