摘　　要：对压力式网前箱的建模进行了介绍 ,并构造了一种新的控制器结构———智能混合控制器 ,将Fuzzy和PID控制相结合 .该控制器可以通过模糊模型来估计未来时刻的误差变化率 ,避免超调或控制过于保守 ;同时还可以根据误差和误差变化率进行选择控制 .将智能混合控制算法用于网前箱的实际控制中 。A model of the pressurized headbox is introduced. We construct a new kind of control system - the intelligent combined control system, including Fuzzy control and PID control. With this system, we can estimate the variety rate of error aftertime through the Fuzzy model avoid overshooting or conservative control, at the same time we also can choose the better controller according to the error and the variety rate of error. We use the intelligent combined method to control pressurized headbox and gain the distinct improvement.
