摘要
介绍了1450 mm冷连轧机前馈及监控AGC的控制策略,提出监控AGC中包含的纯滞后环节会给产品质量带来较大的影响。利用Smith预估算法解决了厚度控制纯滞后的问题,实际生产表明,厚度控制系统的精度和稳定性均有较大提高。
The control strategy of feed-forward control system and AGC monitoring System in 1450 mm tandem cold mill is introduced.It is proposed that the pure time delay occurred in monitoring AGC will have much effect on the quality of cold rolled products.The problem concerning the pure time delay in monitoring AGC is resolved by Smith algorithm method.The actual production results indicate that the precision and stability of AGC monitoring system are improved greatly.
