摘　　要：基于板形测控数学模型和虚拟仪器技术,研制了一种新型的冷轧带钢板形测控系统。首先利用板形仪获得高灵敏度的原始信号,然后根据实际工况计算各种工艺误差,在获得高精度有效板形信号的同时对其进行模式分解和板形调控,观察轧制前后的板形调控效果;其次利用虚拟仪器软件和OPC技术组建虚拟平台,降低硬件风险和设备费用,减少通讯环节和闭环周期,便于组态和调试。工业实例表明,新系统安装方便,易于操作,适应恶劣工况,能够满足在线板形调控要求。Based on the mathematical model and the virtual instrument technology of strip shape,a new detection and control system for the cold rolling strip was developed. Firstly,the original signals with high sensitivity was obtained by the shapemeter,and then the varied process errors were calculated according to the actual conditions to obtain the effective shape signal with high accuracy,meanwhile,the modal decomposition and shape control were conducted,and the effective shape signal effects of the shape control before and after rolling were observed. Secondly,the configuration and debugging were easy to carry out by using the virtual communication platform formed based on the virtual instrument software and the OPC technology,which was helpful to reduce the risk of hardware,the cost of equipment,the communication steps and the closed-loop period of the configuration and commissioning. Industrial examples show that the new system is easy to be installed and operated,and adapts to the harsh conditions to meet the requirements of online shape control.
