A control method was studied based on fuzzy adjacent coupling for multi cylinder synchronous control of leveling system.Firstly,the leveling force system and multi cylinder control system were analyzed,a nonlinear mathematical model of the controlled objects was built.On the adjacent coupling controller design,a compensator was used to fuse the two adjacent hydraulic cylinder position synchronization error controller of hydraulic cylinder,and fuzzy PID control algorithm was used to get the exact compensatio...
