Opis

Computational Methods for the Innovative Design of Electrical Devices is entirely focused on the optimal design of various classes of electrical devices. Emerging new methods, like e.g. those based on genetic algorithms, are presented and applied in the design optimization of different devices and systems. Accordingly, the solution to field analysis problems is based on the use of finite element method, and analytical methods as well. An original aspect of the book is the broad spectrum of applications in the area of electrical engineering, especially electrical machines. This way, traditional design criteria of conventional devices are revisited in a critical way, and some innovative solutions are suggested. In particular, the optimization procedures developed are oriented to three main aspects: shape design, material properties identification, machine optimal behaviour. Topics covered include: New parallel finite-element solvers Response surface method Evolutionary computing Multiobjective optimization Swarm intelligence MEMS applications Identification of magnetic properties of anisotropic laminations Neural networks for non-destructive testing Brushless DC motors, transformers Permanent magnet disc motors, magnetic separators Magnetic levitation systems
