- 在造纸机的加压网前箱控制系统中,通常会出现强耦合和非线性的特性,给系统控制带来困难。
In the pressurized head box control system of paper machine, the characteristic of nonlinear and strong coupling always appears, and makes the system control difficult. - 运用单位矩阵解耦控制方法,解决造纸过程中纸机网前箱系统中纸浆流量和蒸汽压力的耦合问题;
Using the method of unit matrix synthesis to solve the coupling problem between the paper pulp flux and the steam press in the papermaking process. - 针对网前箱的线性模型,设计了网前箱的多变量预测函数控制,并进行了仿真,获得了较好的控制效果。
Based on the linear model of pressurized headbox, multivariable predictive functional control is designed to control the headbox and good performances are achieved.
