Abstract：

Synchronous control system is a key part to ensure the normal operation of forging press and good system performance. A completely hybrid synchronous system based on active rectification and passive rectification was introduced, and a multi-variable mathematical model was built by analyzing the system with Laplace transform method. For multi-variable characteristics, control variables of the system were optimized. And simulation was carried out by MATLAB based on system optimization. The simulation shows that when the beam deflects, the maximum deflection angle of 1.4×10-4 rad appears at 0.015 s, and the moving beam rectification is accomplished by recovering back to horizontal plane at 0.5 s. The result shows that the optimization system model is feasible with fast response performance and good rectification performance.
