Research on Fuzzy Adjacent Coupling Synchronization Control in Multi-cylinder Leveling System

Liu Ruijia;Chen Kai;Liaoning Technical University;  
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 compensation coefficient which was difficult to obtain by conventional method.Through the MATLAB simulation and experiments,the synchronous control method of fuzzy adjacent coupling was tested,and the control of the master slave coupling was used to compare and analyze the results.The results show that the error fluctuation of the four hydraulic cylinders is small,and the errors may be reduced quickly in the hydraulic cylinder plus deceleration phase,which has good synchronization control performance.
