一种基于差分进化理论优化的隐式空间映射算法及其应用
AN IMPLICIT SPACE MAPPING ALGORITHM OPTIMISED WITH DIFFERENTIAL EVOLUTION THEORY AND ITS APPLICATION
摘要
Abstract
False convergence may exists in filter optimisation process of standard implicit space mapping algorithm,it leads to the mapping relationship between coarse-model and fine-model becoming weak and makes the entire optimisation efficiency be low.We propose an improved algorithm,by introducing differential evolution theory it searches the optimal global solution of objective function,and prevents false conver-gence in optimisation process.At last,we apply this algorithm to optimise an LTCC filter with multi-level structure.Experimental results dem-onstrate that the new method aimed at achieving better mapping relationship has less iteration times and costs shorter time under the condition of satisfying the design specifications similarly.It has good feasibility and efficiency.关键词
