Abstract

Abstract: Aiming at engineering optimal design of electromagnetic devices, this paper proposes the optimization method based on a combination of compactly supported radial basis function approximation model and the improved differential evolution algorithm. Model the explicit function of complicated objective function and constraint for multi-dimensional design space structure by Compactly Supported Radial Basis Function（CSRBF）. Obtain the high accuracy global optimal solution by the combination of improved differential evolution algorithm. The analysis result shows that the new method of convergence rate and the optimize efficiency have obvious advantages compared to other random class.
