Abstract：

In order to improve the running stability of multicylinder leveling system for rolling mill and ensure the accuracy of strip production, a hydraulic synchronous control technology of multicylinder leveling system was studied, and the mathematical model of multicylinder synchronous control system was established to determine the linear equation between system load and expansion displacement of each cylinder, as well as the nonlinear equation of load characteristics for synchronous control system. Then, the tracking error of a single cylinder relative to a given cylinder displacement and the synchronization error between adjacent cylinders were comprehensively considered by the ringcoupled multicylinder synchronization control strategy, and an error compensation control algorithm for multicylinder synchronous control based on variable universe fuzzy PID was established by variable universe method. The experimental results show that the mean of the maximum pitch angle of this method is reduced by 14.33%, 3.51% and 11.29% respectively, the mean of the maximum roll angle is reduced by 15.01%, 2.61% and 9.04% respectively, and the mean of the maximum synchronization error is reduced by 17.09%, 5.09% and 9.79% respectively compared with the other three methods. Thus, the feasibility of ring coupled control strategy and variable universe fuzzy PID control algorithm to achieve high precision multicylinder synchronous control technology was verified.
