在秒流量方程的基础上,充分考虑厚度偏差和张力波动对速度的影响,推导并建立了1个冷连轧综合速度控制模型,并根据动态结构图配置了控制器。通过对比仿真研究,进一步优化了控制器参数,在某1 550 mm冷连轧生产应用中,将张力、厚度指标作为控制目标,速度参数作为控制对象,使张力波动从调整前的300 kg减小到目前的90 kg,动态响应效果和板形都得到明显改善,厚度误差也从原先的±5μm提高到了现在的±4μm。 Based on the second flow equation, the influence of thickness deviation and tension fluctuation on speed is fully considered, and a comprehensive control model of cold tandem rolling speed is deduced and established. The controller is configured according to the dynamic structure diagram. Through comparative simulation study, the parameters of the controller are further optimized. In a 1 550 mm tandem cold rolling mill, the tension and thickness indicators are taken as the control targets and the speed parameters are taken as the control targets to reduce the tension fluctuation from 300 kg before adjustment The current 90 kg, dynamic response and shape have been significantly improved, the thickness error from the original ± 5μm increased to the present ± 4μm.
