摘　　要：为了降低薄板烘丝机排潮负压的变异系数,解决负压检测管路周期反吹影响每批次的变异系数值。对料头和生产过程中反吹时采用不同的预测函数控制嵌入到PID控制,对薄板烘丝机排潮压力值变异系数进行控制,实验结果多项式函数预测效果略优于动态函数预测效果,有效地降低了每批次排潮压力的变异系数。In order to reduce the coefficient of variation of the negative pressure of the damp discharge of the thin-plate dryer,it is solved that the negative pressure detection pipeline periodically blows back to affect the coefficient of variation of each batch.Different predictive functions are used to control the feed head and the production process when backflushing is embedded in the PID control,and the coefficient of variation of the moisture pressure value of the thin-plate dryer is controlled.The experimental results polynomial function prediction effect is slightly better than the dynamic function prediction effect.It reduces the coefficient of variation of the tidal pressure of each batch.
