A mathematical model of synchronous control system for giant forging hydraulic press was established. On this basis, a servo compensator with good dynamic performance was proposed under the premise of ensuring system stability. The simulation results show that the proposed control algorithm can effectively solve the problem of synchronous control of giant forging hydraulic presses driven by multiple cylinders, and has strong robustness and good dynamic performance. At the same time, the fluctuation of the robust control parameters of the synchronous system is analyzed. The results show that the synchronous control system has a very good robustness to the fluctuations of the nonlinear parameters of the system under the effect of the robust regulator. Very good to eliminate the system synchronization error.
