介绍了闪光焊机的液压系统的组成及其工作原理，建立了闪光焊机液压系统的数学模型。针对闪光焊接的顶锻阶段，提出了一种基于二级模糊自调整PID的控制模型，第一级模糊PID控制应用于基准通道，第二级模糊PID控制应用于同步通道，实时地调整PID参数以达到系统的同步运动，该控制方法有效减少了两个系统的压力动态同步误差。

The configuration and working principle of hydraulic system of flash butt welder were presented,and the mathematic model of hydraulic system of flash butt welder was established.The control model based on two-class fuzzy self-adjustment Proportion-Integral-Differential (PID)was introduced by aiming at the top-forging stage of the flash butt welding.The First-class fuzzy PID con-trol was used for benchmark access,and the second-class for simultaneous access,the PID parameters were adjusted in real-time to a-chieve simultaneous movement of the system.The control methods are effective in reducing the synchronous dynamic error of pressure on the two systems.
