对盾构推进系统的液压缸采用分区控制，以达到降低系统复杂程度、保证控制精度的目的。用液压仿真软件AM ESim对推进液压系统进行仿真模拟分析，采用开环与闭环两种方式。仿真结果表明，压力流量闭环控制较开环控制可以有效减少压力和流量的波动，实时控制推进压力和推进速度，控制效果较好。
對盾構推進繫統的液壓缸採用分區控製，以達到降低繫統複雜程度、保證控製精度的目的。用液壓倣真軟件AM ESim對推進液壓繫統進行倣真模擬分析，採用開環與閉環兩種方式。倣真結果錶明，壓力流量閉環控製較開環控製可以有效減少壓力和流量的波動，實時控製推進壓力和推進速度，控製效果較好。

In this paper ,the hydraulic cylinder of shield thrust system is controlled by partition ,to reduce the complexity of the system and ensure the accuracy of control . The simulation analysis on the thrust hydraulic system is carried out by hydraulic simulation software AMESim ,which is controlled by open loop and closed loop respectively .The results show that :compared with open loop control , the pressure-flow closed loop control can effectively reduce the pressure and flow fluctuations , control the pressure and velocity in real time ,the control effect is better .
