Forging hydraulic press needs good rigidity during working process,so two hydraulic cylinders are generally driven synchronously.In order to ensure precise synchronization of the two driving hydraulic cylinders in the working process of the forging hydraulic press,BP neural network PID adaptive control method was adopted to synchronously control the driving hydraulic cylinders of the forging hydraulic press.AMESim and MATLAB were used to build the simulation model of the forging hydraulic press.The synchronization performance simulation of the two driving hydraulic cylinders was carried out under the conditions of constant load,continuous changing load and step changing load.The simulation results show that under various stress conditions of the two driving hydraulic cylinders of the forging hydraulic press,the system can better realize the synchronous control of the two driving hydraulic cylinders,and the maximum displacement error is only 0.6 mm,which meets the work of the forging hydraulic press.The system has good synchronization control precision and robustness.
