摘要
讨论了模态实验中传感器的配置问题 ,以模态置信度矩阵的最大非对角元为目标函数 ,重点研究了组合优化问题中的遗传算法 ,针对组合优化中约束条件的满足问题提出了二重结构编码遗传算法 ,并将这种方法应用于海洋平台的传感器配置中 ,与序列法作了比较 ,取得了较好的优化效果。
This paper describes a sensor placement algorithm in Model test.Taking the maximum off-diagonal element of Modal Assurance Criterion (MAC) matrix as target function, the genetic algorithm emphatically in combinatorial optimization is studied,and dualistic coding genetic algorithm aiming at restriction problem in combinatorial optimization is presented. The algorithm is used in sensor placement of an offshore platform and compared with serial algorithm, which shows the dualistic coding genetic algorithm is effective in optimization.[
