Vector Control of AC Drives
by Syed A. NasarAlternating current (AC) induction and synchronous machines are frequently used in variable speed drives with applications ranging from computer peripherals, robotics, and machine tools to railway traction, ship propulsion, and rolling mills. The notable impact of vector control of AC drives on most traditional and new technologies, the multitude of practical configurations proposed, and the absence of books treating this subject as a whole with a unified approach were the driving forces behind the creation of this book. Vector Control of AC Drives examines the remarkable progress achieved worldwide in vector control from its introduction in 1969 to the current technology. The book unifies the treatment of vector control of induction and synchronous motor drives using the concepts of general flux orientation and the feed-forward (indirect) and feedback (direct) voltage and current vector control. The concept of torque vector control is also introduced and applied to all AC motors. AC models for drive applications developed in complex variables (space phasors), both for induction and synchronous motors, are used throughout the book. Numerous practical implementations of vector control are described in considerable detail, followed by representative digital simulations and test results taken from the recent literature.Vector Control of AC Drives will be a welcome addition to the reference collections of electrical and mechanical engineers involved with machine and system design.
Vector Control of Induction Machines
by Bruno Francois Philippe Degobert Benoît Robyns Jean Paul HautierAfter a brief introduction to the main law of physics and fundamental concepts inherent in electromechanical conversion, Vector Control of Induction Machines introduces the standard mathematical models for induction machines - whichever rotor technology is used - as well as several squirrel-cage induction machine vector-control strategies. The use of causal ordering graphs allows systematization of the design stage, as well as standardization of the structure of control devices. Vector Control of Induction Machines suggests a unique approach aimed at reducing parameter sensitivity for vector controls based on a theoretical analysis of this sensitivity. This analysis naturally leads to the introduction of control strategies that are based on the combination of different controls with different robustness properties, through the use of fuzzy logic supervisors. Numerous applications and experiments confirm the validity of this simple solution, which is both reproducible and applicable to other complex systems. Vector Control of Induction Machines is written for researchers and postgraduate students in electrical engineering and motor drive design.
Vector Control of Three-Phase AC Machines

The Vegan
by Andrew LipsteinHerschel Caine is a master of the universe. His hedge fund, built on the miracle of machine learning, is inches away from systematically sapping profits from the market. His SoHo offices (shoes optional, therapy required) are ready for desperate investors to flood through the doors. But on May 12, his mind is elsewhere-at his Cobble Hill townhouse and the dinner party designed to impress his flawless neighbours. When the soiree falters, Herschel concocts a prank that goes horrifically awry, plunging him into a tailspin of guilt and regret. As Herschel's perfect world starts to slip away, he clings to the moral clarity he finds in the last place he'd expect: a sudden connection with his neighbour's dog.A wildly inventive, reality-bending trip, The Vegan holds a mirror up to its reader and poses a question only a hedge fund manager could: is purity a convertible asset? The more Herschel disavows his original sin, and the more it threatens to be revealed, the more it becomes something else entirely: a way into a forgotten world of animals, nature, and life beyond words. Andrew Lipstein, the author of Last Resort, a novel that 'you'll think about . . . for weeks after you read the last pages' (Los Angeles Times), challenges our ideas of contemporary morality in his scintillating, provocative second novel.
Vegan Alternatives for Leather (Sustainable Textiles: Production, Processing, Manufacturing & Chemistry)
by Subramanian Senthilkannan Muthu Mukta RamchandaniEnvironmental toxicity and sustainability are major areas of research for the leather industry, as well as for the larger luxury and fashion industry.
