Book Synopsis Advanced Direct Thrust Force Control of Linear Permanent Magnet Synchronous Motor by : Muhammad Ali Masood Cheema
Download or read book Advanced Direct Thrust Force Control of Linear Permanent Magnet Synchronous Motor written by Muhammad Ali Masood Cheema and published by Springer Nature. This book was released on 2020-02-13 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the direct thrust force control (DTFC) of tubular surface-mount linear permanent magnet synchronous motors (linear PMSMs). It presents a detailed account and analysis of several advanced nonlinear control schemes, based on the direct thrust control principle, to achieve a reduction in steady-state ripple in thrust force with faster transient response, and describes their experimental validation. It also provides rigorous details of the dynamic modelling of linear PMSMs from a control system perspective, and demonstrates the superior control performance of the proposed techniques compared to the current state-of-the-art techniques. Lastly, the book proposes and validates a stator flux observer for sensorless speed estimation comprising a linear state observer and an improved sliding mode component.

Book Synopsis The Rediscovery of Synchronous Reluctance and Ferrite Permanent Magnet Motors by : Gianmario Pellegrino
Download or read book The Rediscovery of Synchronous Reluctance and Ferrite Permanent Magnet Motors written by Gianmario Pellegrino and published by Springer. This book was released on 2016-04-28 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an essential compendium on the analysis and design of synchronous motors for variable-speed applications. Focusing on synchronous reluctance and ferrite permanent-magnet (PM) synchronous reluctance machines, it provides a broad perspective on three-phase machines for variable speed applications, a field currently dominated by asynchronous machines and rare-earth PM synchronous machines. It also describes synchronous reluctance machines and PM machines without rare-earth materials, comparing them to state-of-the-art solutions. The book provides readers with extensive information on and finite element models of PM synchronous machines, including all relevant equations and with an emphasis on synchronous-reluctance and PM-assisted synchronous-reluctance machines. It covers ferrite-assisted machines, modeled as a subcase of PM-assistance, fractional slot combinations solutions, and a quantitative, normalized comparison of torque capability with benchmark PM machines. The book discusses a wealth of techniques for identifying machine parameters, with an emphasis on self-commissioning algorithms, and presents methods for automated machine design and optimization, including a software tool developed for this purpose. Addressing an important gap in the field of PM-less and less-PM electrical machines, it is intended as a self-contained reference guide for both graduate students and professional machine designers, and as a useful text for university courses on automated and/or optimized design of electrical machines and drives.
