| 摘 要： | Abstract: The brief arts and crafts of the ordinary fourdrinier are introduced first. After the intractable points of paperbasis weight (BW) control are analyzed, an autotuning PID/PI control algorithm based on relay feedback identification isproposed, which has such advantages as simple parameter adjustment, little dependence on process model, strong robustness andeasiness to implementation. And it is very suitable for controlling such processes as BW loop with large time delay. |
