Abstract：

The traditional synchronous control of hydraulic press needs longer time to reach the steady-state error and can not achieve the high precision synchronous control of hydraulic press. In order to improve the working efficiency of hydraulic press, a synchronous control hydraulic system of hydraulic press with double cylinders was developed, and the control schemes of piston rod in two states for extension and retraction were given. The synchronization error compensation data was transmitted to hydraulic cylinder 2 to complete the dynamic response faster, so as to significantly reduce the displacement difference of hydraulic cylinder 2 and achieve a significant improvement in the synchronization control accuracy. Furthermore, the synchronous control was realized by the error feedback method to achieve the precise control of the synchronous operation process of double hydraulic cylinders, and the PID parameters were adjusted by the genetic algorithm to significantly improve the synchronous control precision of double-cylinder hydraulic system. Compared with the parallel control methods, the error feedback synchronous control method reduced the maximum error by 68.71% and reduced the time required to enter the steady state error by 18.52%. Thus, the precise synchronous control of the hydraulic press could be realized by the synchronous control structure.
