Abstract：

In order to improve the precision of double cylinder hydraulic synchronization control for forging press and ensure the quality of forging parts, the model of double cylinder hydraulic synchronization electro-hydraulic servo control system for forging press was simplified, the model of synchronization control system was deduced, and the control objective equation was obtained. Then, the single neuron PID control algorithm and the cross-coupling algorithm were used as the synchronous control algorithms of double-cylinder hydraulic system for forging press, and the position tracking error of left and right hydraulic cylinders for forging press, relative synchronous control error and tracking error of speed and pressure for hydraulic cylinders under the action of conventional fuzzy PID control algorithm and fuzzy-single neuron PID control algorithm were get and compared by simulation. The results show that the system of fuzzy-single neuron PID control algorithm converges faster than that of the conventional fuzzy PID control algorithm, and the fuzzy-single neuron PID control algorithm makes the double cylinder hydraulic synchronous electro-hydraulic servo control system of forging press more robust. Furthermore, the experimental results are consistent with the simulation results, and the error between them is less than 10% to verify the feasibility of the proposed double cylinder hydraulic synchronization control method for forging press.
