A synchronous control system is proposed to solve the problem of position deviation caused by driving hydraulic cylinder during the execution of hydraulic press.The basic structure and technical parameters of the hydraulic press are described,the hydraulic system schematic diagram is drawn by FluidSIM software,and the simulation analysis is carried out.The mathematical model of multi-cylinder driven hydraulic press is established,and the PID control link is optimized.With sensor and electromagnetic proportional directional valve as the hardware core,the simulation model of synchronous control system with PID control link is built by AMESim,on which the simulation experiment is conducted.The experimental results show that the application of fuzzy PID control system improves the synchronization accuracy and operation stability of hydraulic multi-cylinder system.
