摘要
为了有效提高现代船舶通信节点参数实时提取时的控制性,将小生境遗传算法应用于船舶通信节点参数提取中,提出新的提取方案。基于当前船舶通信节点参数,构建小生境遗传PID算法,完成通信节点参数初始化和交叉节点变异,构建适应性参数集,引入节点参数染色体规划方法,完成通信节点参数集编码和数据划分,对于不支持均匀分配的通信节点设置特殊编码,设定聚合函数根据染色体编码规则重新设定度量值,完成节点参数数据的筛选聚合,根据最终的聚合值正向排序,实现通信节点参数实时提取。实验数据表明,应用小生境遗传算法构建的船舶通信节点参数提取方案,参数提取进化次数降低了20%以上,参数提取稳态响应率提高了25%,整体控制性更强。
In order to effectively improve the control of real-time extraction of ship communication node parameters,niche genetic algorithm was applied to the extraction of ship communication node parameters,and a new extraction scheme was proposed.Parameters based on the current Marine communication nodes,and build a niche genetic algorithm PID,complete the communication node parameter initialization and cross variation,an adaptive parameter set,the introduction of node parameters chromosome planning method,complete the communication node parameter set encoding and data partitioning,for does not support evenly distributed communication node set special coding,set aggregation function according to the chromosome encoding rules to set measurement,screening the node parameter data aggregation,according to the final aggregate values are sorted,realize real-time communications node parameters extraction.Experimental data show that the evolution times of parameter extraction are reduced by more than 20%,the steady response rate of parameter extraction is increased by 25%,and the overall control is stronger.
