摘　　要：以超高强钢热冲压生产过程中温度的变化为研究对象,为了提升热冲压零件的稳定性、降低温度变化对零件性能的影响,提出了一种通用的长周期智能控制模型,并聚焦热冲压生产中的长周期因素,基于信息物理系统的传感数据,采用在线长周期智能控制方法,对热冲压成形工艺的模具温度和冷却水温度进行优化控制。通过在生产线中构建传感器网络,并对模具温度和冷却水温度进行监测和主动调节,长周期智能控制方法不仅实现了模具温度和冷却水温度的优化控制,还能够将生产节拍智能调整到较为合理的数值,是一种有效的动态控制方法。长周期智能控制是对现有热冲压生产控制系统的有益补充。For the change of temperature during the hot stamping production process of ultra-high-strength steel,in order to improve the stability of hot stamped parts and reduce the influences of temperature changes on the performance of parts,a general long-period intelligent control model was proposed,and the long-period factors in hot stamping production were focused on.Based on the sensing data from cyberphysical system,the die temperature and the cooling water temperature in the hot stamping process were optimally controlled by the on-line long-period intelligent control method.Through building a sensor network in the production line and monitoring and actively adjusting the die temperature and the cooling water temperature,the long-period intelligent control method not only realized the optimal control of the die temperature and the cooling water temperature,but also intelligently adjusted the production cycle to a more reasonable value,which was an effective dynamic control method.Thus,the long-period intelligent control is a useful supplement to the existing hot stamping production control system.
