In addition, these types of SLSRM have some other advantages, like simpler configuration, cooling in easier way, etc. Firstly an analytical design is carried out to illustrate the design procedure and then three-dimensional (3-D) magneto static simulation analysis of the SLSRM and the one layer SRM is performed using 3-D FEM, to obtain and. As with the previous editions of this book,the authors wrote it to: 1) Balance the coverage of concepts,tools,techniques,and their applications 2) Provide the most examples of system analysis and design deliverables available in any book 3) Balance the coverage of classical methods (such as structured analysis and information engineering) and 4/5(2).

Abstract: As the first part of the "Low noise design of fan outlet guide vane" serial articles, this paper proposes an integrated aerodynamic and acoustic design method.
The influence of axial sweep and circumferential lean of Outlet Guide Vane (OGV) on the rotor wake/stator interaction noise of a modern high-bypass ratio fan stage is investigated. mented with stator-resistance adaptation, based on the fun-damental excitation, and analytical stability conditions and design rules are derived for the augmented observer.
Based on these stability conditions, an easy-to-tune observer design is proposed. The proposed design is very simple, and it results in a robust and well-damped closed-loop.
