For the problems of poor tracking performance, slow dynamic response and low synchronization control precision caused by nonlinear and time-varying in the electro-hydraulic position synchronization control system of metal processing and forming equipment, taking the valve controlled asymmetric cylinder system as the researching object, the double-cylinder position synchronization control model was established based on the working principle of electro-hydraulic servo system, and the control algorithm of integral separation PID neural network after feedforward correction was proposed. Then, the double-cylinder position synchronization controller was designed, and its simulation analysis was conducted. The simulation result indicates that using this method restrains the interference effectively such as load changes, ambient temperature changes and non-linearity of hydraulic components during the equipment operation, and the double-cylinder position synchronization error is controlled within 0.1 mm. In addition, the system shows good dynamic tracking performance and short adjustment time to improve the shortcomings of traditional control method.
