摘　　要：借鉴生物免疫系统异常识别能力相关研究,基于具有自治、自适应和演化能力的人工免疫理论与方法,对大型结构健康监测中的故障检测和分类问题进行研究,提出一种基于粒子群优化变异的克隆选择算法.该算法将样本结构模式数据作为抗原刺激抗体集合,抗体集合经过克隆、变异、选择等学习和进化过程以提高记忆细胞质量,以实现对实测数据的故障检测与分类.特别是针对克隆选择算法二进制编码复杂和变异方向不确定的问题,引入了粒子群优化变异.在Benchmark结构模型上的仿真实验结果表明该算法有效地识别故障模式,且提高了结构故障分类的成功率.Inspired by a study on the ability of biological immune systems to identify antigens, we investigated adam- age detection and classification problem in the health monitoring of large-scale structures and proposed a clone- selection algorithm of particle swarm mutation based on the autonomous, adaptive, and evolutional artificial im- mune theory and method. The algorithm sampled data from a structure model of an antigen that stimulates anti- body sets. To improve the quality of the memory cells and achieve damage detection and classification of the measured data, the antibodies go through a learning and evolving process that included cloning, mutation, and selection. In particular, particle swarm mutation was introduced to solve the problem of binary encoding com- plexity and the uncertainty of the mutation direction in the clone selection algorithm. The experimental results obtained for the proposed algorithm using the Benchmark structure model indicated that the algorithm could ef- fectively identify failure modes and improve the success rate of structure damage classification.
