PCBA生产手工插件线产品质量易受人工操作水平等因素影响,且多个产品质量检测环节均在手工插件线末端,导致难以在生产过程中及时把控产品质量。为了及早发现手工插件线的产品质量问题,提出了基于LSTM的PCBA产品批次质量多步预测控制策略,将手工插件线上的FCT质量检测数据经过处理后作为模型的输入特征,建立了基于LSTM的PCBA批次质量预测模型。最后,将所建立的预测模型与BP、RNN和SVR模型以及目前在数据特征分析拟合上表现较好的CNN模型进行比较,仿真结果表明,所提出的模型在电子产品质量的预测中具有更好的效果,可以为PCBA的质量调控提供指导。

基于分层剥离试验的温拌橡胶沥青改性机理研究

第35届中国过程控制会议

作者： yu Hui Ronghu Chi School of Automation & Electronic Engineering Qingdao University of Science & Technology

This work develops a data-driven adaptive iterative learning control(DDAILC) for output tracking problem of linear time-varying singular systems. By differencing system outputs between different iterations, the iterative dynamic relationship(IDR) between input and output data is established. Based on IDR, two index functions about the unknown system parameter and control input are designed, through which the parameter updating law and learning control law are proposed based on optimization design. The learning gain is updated by the parameter estimation automatically. The proposed DDAILC is data based and does not depend on the explicit system model. The effectiveness of the proposed method is verified by simulation studies.

为探究温拌橡胶沥青(WAR)的性能影响机理,选取70#基质沥青、2种温拌剂和2种粒径的胶粉,制备了2种橡胶沥青(AR)和4种温拌橡胶沥青。通过固液相分离得到制备沥青样品的液态组分和不溶胶粉,创新性地利用分层剥离法对不溶胶粉混溶区成分进行逐层提取,通过试验研究建立胶粉吸附偏好特性与橡胶沥青高、中温流变性能间的联系,明确温拌橡胶沥青的改性机理。试验结果表明:橡胶沥青高温抗车辙性能和低温抗开裂性能的提升得益于不溶胶粉在沥青中产生的颗粒效应和可溶胶粉成分发挥的改性作用;橡胶沥青中温耐久性能的提高和黏度的增大主要归因于不溶胶粉中产生的颗粒效应;不同类型温拌剂对橡胶沥青流变性能的影响有所区别。有机类温拌剂的加入在提升橡胶沥青的高温抗车辙性能和中温耐久性能方面更为显著;化学类温拌剂的加入则在提升橡胶沥青的低温抗开裂性能方面更为有效;橡胶沥青液态组分中具有较小的相对分子质量的轻质成分更容易被胶粉吸附至其混溶区中;有机类温拌剂对胶粉的吸附偏好性几乎没有明显影响,而化学类温拌剂的加入不仅减少了液态组分中较大相对分子质量成分的比例,还削弱了胶粉的吸附偏好性;胶粉的吸附偏好性有利于提高橡胶沥青的高温性能和耐久性能。
