摘要
为解决电磁场逆问题分析计算过度依赖计算机资源这一"瓶颈"问题,提出了一种新的快速全局优化算法。该算法首先应用基于紧支集径向基函数(CS-RBF)的改进表面响应模型(RSM)重构原优化问题;然后应用改进的粒子群算法(PSO)对重构的优化问题进行快速全局寻优。研究表明,典型数学函数验证以及电磁场逆问题的分析和计算,验证了算法的全局搜索和快速寻优能力。
To release the requirement for tremendously heavy computation resources in the study of electromagnetic inverse problems, a fast global optimizer was proposed, based on the combination of the improved response surface mode (RSM) using compactly support radial basis functions (CS-RBF) and an improved particle swarm optimization(PSO). Computer simulation results on a machematical function and a practical engineering design problem were presented to demonstrate the efficiency and robustness of the proposed algorithm.
