摘　　要：为了降低液压缸位置闭环控制系统的成本,该文将普通方向阀引入到扇形段辊缝液压缸位置闭环调节控制系统中,采用Simulink仿真软件建立了系统的仿真模型,并对该模型进行了仿真分析及现场实验。仿真与实验结果基本一致,证明所建立模型的正确性及参数设置的合理性,为后续的普通方向阀控制位置闭环系统的开发提供了较高的参考价值。In order to reduce the cost of hydraulic cylinder position closed-loop control system,this thesis introduces normal direction valveinto roll gap control system of segment,establishes simulation mode of the system by adopting Simulink simulation software and conductssimulated analysis as well as field experimentation to this model.The simulation basically consists with the results of experimentation,which proves the correctness of the model established as well as the rationality of the parameter setting and provides greater reference valueto subsequent development of normal direction valve controlling position closed-loop system.
