摘　　要：针对纸张定量水分的控制难点,提出定量串级加前馈的控制方案,并对定量和水分进行解耦,同时采用目标值自适应控制,使纸页定量和水分分布的峰值保持在允许的最小值与最大值的范围内。Aimed to the control difficulties of basis weight and moisture in papermaking process, proposed a cascade and feed forward control scheme, and decoupled the coupling relationship between basis weight and moisture, and used target adaptive control, which can make the peak of basis weight and moisture keep on the least or maximum value, and it realized economic benefits.
