铜闪速熔炼过程操作模式快速匹配策略

Operational pattern fast matching strategy for copper flash smelting process

在利用相似模式的归纳与综合实现铜闪速熔炼过程多操作参数同步优化的过程中,针对模式库庞大引起相似模式发现效率低的问题,提出了两级模式快速匹配方法.该方法采用主元分析实现属性权重设定,通过构造模式间相似性度量准则,并在初级匹配准则中引入柯西不等式,以减少计算复杂度,快速缩小次级匹配的搜索范围,提高模式匹配速度.UCI数据集仿真和实际生产数据应用结果验证了该方法的有效性和可行性.

The operational parameters can be optimized synchronously by inducting and synthesizing similar operational patterns. For the drawback of the low efficiency of pattern matching cased by huge pattern case, a two-state pattern matching quickly strategy is proposed. The attribute weights are set by using principal component analysis（PCA） in advance, and the similarity measure between patterns is also constructed. In order to improve the pattern matching speed, the Cauchy-Schwarz inequality is introduced in primary pattern matching, which can be used to reduce the computational complexity and narrow the searching scope for secondary pattern matching. Simulation results based on UCI data sets and actual running data collected from a copper flash smelting process are given to verify the effectiveness and feasibility.
