置信区间渐进空间映射算法优化设计共形微带天线

摘要

介绍了一种快速收敛的置信区间渐进空间映射算法.将置信区间的概念和渐进空间映射算法结合在一起,进一步加快精细模型与设计目标的逼近速度,提高了优化效率,通过此算法设计了一个谐振频率在2.5GHz的柱面共形微带天线.与先前的渐进空间映射算法相比,该方法进一步减少了计算时间,提高了设计效率.%A trust region aggressive space mapping algorithm is presented, the algorithm (TRASM) integrates a trust region methodology with the aggressive space mapping (ASM), it avoids false con-vergence in the optimization of surrogate model and speeds up the approximation between fine model and design object. And then the algorithm (TRASM) is used in the optimized conformal antenna with resonant frequency 2.5 GHz is designed. The results are better than the design specifications. The new algorithm is verified faster and more efficient.
