A new concept for optimal design method considering modeling accuracy of electromagnetic device

Optimal design techniques, which consist of numerical analysis and optimization technique, are commonly used for enhancing the efficiency and for reducing the noise of electromagnetic device. In the optimal design techniques, it is required that the exact solution of the analysis and the precise characteristic of the electromagnetic devices should be obtained. However, usually it is impossible to make the exact model of an electromagnetic device and to remove the numerical error of the numerical analysis. This is one of the reasons why the optimal design techniques has not been more widely utilized. In this paper, a new concept for optimal design considering the accuracy of the analysis is proposed. The proposed optimal design method considers the accuracy of the analysis and indicates multiple solutions. To verify its usefulness, in this paper, an example using the proposed method is shown.
