摘要：

同步控制系统是保证模锻压机正常工作和系统性能的关键部分。介绍了一种基于主动纠偏和被动纠偏的完全混合同步系统，利用拉普拉斯变换法，通过分析该系统建立了多变量数学模型。针对多变量特点，对其进行了控制变量优化。并在系统优化基础上，利用MATLAB软件进行仿真。仿真结果显示，横梁偏转0.015 s时出现最大偏转角为1.4×10-4 rad，0.5 s完成纠偏达到水平状态。实验结果表明，该优化系统模型可行，能够快速响应且纠偏效果良好。

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.
