摘要:

在分析工作原理的基础上，建立了泥水平衡盾构开挖面平衡控制系统的数学模型，为该系统中的气泡舱气压力调节回路和泥水液位调节回路设计了不同的控制器，分别在气泡舱气压力单回路调节模式和气、液双回路调节模式下就所设计的不同控制器的控制效果进行了仿真对比，得出了不同干扰对系统的影响情况，针对影响较大的干扰，提出了相应的控制对策，给出了根据不同的实际应用要求和场合所应选择的最佳控制方式和自动切换方法，由此设计出该系统的数字化统一控制模型。

Abstract:

Based on analysis of the working mechanism，the mathematical model of balance control system for excavating face of slurry shield was founded. Controllers that will be applied to control the pressure of the gases in the bubble cabin and to control the level of the slurry were designed. Simulation of these different controllers designed was carried out respectively in employed alone or combined situations for comparison. The influence of the disturbance to the control system was analyzed, and the way to deal with it was given. The best control method and the automatic shift way according to the different situation were also presented to give the unified digital control model.
