近年来,以物理信息神经网络(PINNs)为代表的人工智能计算范式在等离子体数值模拟领域获得了极大关注,但相关研究考虑的等离子体化学体系较为简化,且基于PINNs求解更为复杂的多粒子低温等离子体流体模型的研究还尚处空白.本文提出了一个通用的PINNs框架(源项解耦PINNs,Std-PINNs),用于求解多粒子低温等离子体流体模型.Std-PINNs通过引入等效正离子,并将电流连续性方程替代各粒子输运方程作为物理约束,实现了重粒子输运方程源项与电子密度、平均电子能量的解耦,极大降低了训练复杂度.本文通过两个经典放电案例(低气压氩气辉光放电、大气压氦气辉光放电)展示了Std-PINNs在求解多粒子低温等离子体流体模型的应用,并将结果与传统PINNs和有限元(FEM)模型进行了对比.结果显示,传统PINNs输出了完全错误的训练结果,而Std-PINNs与FEM结果之间的L2相对误差能达到约10–2量级,由此验证了Std-PINNs在模拟多粒子等离子体流体模型的可行性.Std-PINNs为低温等离子体模拟提供了新的思路,并拓展了深度学习方法在复杂物理系统建模中的应用.

工业过程运行状态评估方法是对过程当前运行状态进行合理的评价,为工业过程的安全、高效运行提供有益的指导.带钢轧制过程具有流程长且系统层级多等特点,而传统的运行状态评估往往采用集中式的评估方法,难以对轧制过程全流程的运行状态进行合理的评估.针对此问题,提出一种融合分层分块信息的轧制过程运行状态评估方法.采用一种多层级分块的评估策略,将全流程分为若干个层级和子块,提高评估结果的可解释性.提出一种联合核主成分分析(kernel principal component analysis,KPCA)和t-分布随机邻域嵌入算法(t-distributed stochastic neighbor embedding,t-SNE)的特征提取方法,并行地提取全局和局部的特征信息.进而,针对传统支持向量机(support vector machine,SVM)输出结果为硬判型输出,将SVM的输出结果映射为后验概率,并通过D-S证据理论融合多个层级的运行状态评估结果,从而实现决策层面的信息融合,提高评估结果的准确性.最后,将所提出方法应用于实际带钢轧制过程,与各类传统的方法相比评估准确率提高近18%.
