摘　　要：目前国外企业已在无缝钢管轧机中普遍采用电液伺服压下系统,而国内生产的无缝钢管轧机主要采用机械压下方式。为提高无缝钢管压下系统在大负载扰动下的定位精度与动态刚度,分别提出了基于伺服阀压力增益特性的负载扰动前馈补偿和抗积分饱和复合控制方案与基于油液压缩效应的动态位置误差流量前馈补偿控制策略。通过AMESim软件建立仿真模型分析压下活塞位移对冲击载荷的响应,进而由试验结果验证所建模型的准确性。该文为电液伺服压下系统的设计提供了一定的理论和试验依据。At present,foreign enterprises have been widely used in electro-hydraulic servo system pressure seamless steel mill,while domestic production of seamless steel mill mainly by mechanical pressure mode.For improving the positioning precision seamless steel pressure in the large and dynamic stiffness of the load disturbance,were proposed based on the gain characteristics of the servo valve pressure load disturbance feedforward compensation and anti-windup control scheme based composite fluid dynamic compression effects former position error flow feedforward compensation control strategy.We using AMESim software framing a simulation model to analysis pressure piston displacement response to shock loads,and by testing it to verify its validity.This article is designed to provides a theoretical and experimental basis for electro-hydraulic servo pressure system.
