Coupled circuits model combined with deteministic and stochastic algorithms for the inductor design

Abstract

In this paper, we present a model dedicated to the resolution of the inverse problem concerning the design and the dimensioning of an inductor which generates a desired magnetic field. The algorithms of optimization are combined with a semi analytical model which is based on the coupled circuit's theory. The latter makes it possible to predict the distribution of the currents density in the turns of the inductor and then to determine its electrical resistance and inductance. Therefore, it lends itself well to the optimization of the inductor parameters.A comparative study between the use of a deterministic algorithm and another stochastic type of Simulated Annealing will be presented. The results obtained show that this approach is effective, precise and especially very fast for the optimization of the inductor parameters.

Nondestructive Eddy Current Measurement of Coating Thickness of Aeronautical Construction Materials

“…In this paper we have exploit the deterministic method that we have recently developed for non-destructive evaluation of coating thickness aircraft construction materials [6]. So, after implementing and running the inversion technique under Matlab environment, the simulation results has shown its rapidity and robustness while making a judicious configuration choice for initial parameters such as initial interval search and tolerance.…”

“…On other hand, the finite element method (FEM) is applicable to any complex devices without restrictions, but it's relatively slow in comparison to the analytical ones. For this reason, our effort is mainly focused on the application of the coupled electric field method (CEFM) that we have recently developed and performed because itis fast and can take into consideration both skin and proximity effects [6]. In this paper, our goal is to associate the coupled circuit method and a new deterministic optimization method that we have recently developed for measuring the nonconductive coating thickness of Al, AU4G, Ti and Inox-304L sheet metals [7].…”
