摘　　要：通过对酒钢板坯连铸机在生产过程中出现的二冷气调节震荡原因分析,确认引起调节震荡的主要原因为当外围管路气压波动时,常规的PID控制不能对调节参数进行实时整定。采用基于神经网络的PID控制方案,较好地解决了调节参数自动整定的问题,使调节效果大为改善,提高了板坯产品质量,取得了良好的生产效果。Based on the slab caster JISCO process in the production of the secondary cooling air vibration analysis, confirmed regulation cited the main reason for the shocks from the external line when the pressure fluctuations, that is the conventional PID control can not adjust the parameters of real-time auto tuning. Neural network-based PID control scheme was used,and the better solution of the regulation of auto-tuning parameters of the problem was got, so that the regulation effect was greatly improved, the slab quality of products was improved, and achieved good results in the production.
