摘要：

考虑到轧机双驱进给系统的液压缸同步控制误差对于轧机生产带板的板形和精度影响较大，研究了轧机下压轧辊的双驱进给系统液压同步控制技术,分析了双驱进给系统的工作原理，并建立了双驱进给系统同步控制模型以及基于模糊PID算法的轧机双驱进给系统同步控制方法。仿真结果表明：在模糊PID控制策略作用下，进给液压缸的最大跟踪和同步误差分别为6.2和2.5 mm，均低于在常规PID控制策略作用下的最大跟踪和同步误差；轧机双驱进给平台的最大倾角和平均倾角为0.215°和0.11°，均低于在常规PID控制策略作用下的最大倾角和平均倾角；轧机双驱进给液压缸的动作基本一致，而常规PID控制策略作用下轧机双驱进给液压缸2的动作要明显滞后于进给液压缸1的动作。研究结果为轧机双驱进给系统的设计提供了参考。

Considering that the synchronous control error of hydraulic cylinder in the double-drive feeding system of rolling mill has a great influence on the shape and accuracy of strip produced by the rolling mill, the hydraulic synchronous control technology of the double-drive feeding system for the down-pressing roller of rolling mill was studied. Then, the working principle of double-drive feeding system was analyzed, and the synchronization control model of double-drive feeding system and the synchronization control method of double-drive feeding system of rolling mill based on fuzzy PID algorithm were established. The simulation results show that the maximum tracking and synchronization errors of the feeding hydraulic cylinder are 6.2 and 2.5 mm respectively under the action of fuzzy PID control strategy, which are lower than that under the action of conventional PID control strategy. The maximum inclination and average inclination of the double-drive feeding platform of rolling mill are 0.215° and 0.11°, respectively, which are lower than that under the action of conventional PID control strategy. The actions of double-drive feeding hydraulic cylinder of rolling mill are basically the same, but the action of double-drive feeding hydraulic cylinder 2 of rolling mill is obviously lagged behind that of the feeding hydraulic cylinder 1 under the action of conventional PID control strategy. The research results provide a reference for the design of double-drive feeding system of rolling mill.
