【摘要】：以在南昌地鐵1號線艾溪湖東站至艾溪湖西站區(qū)間施工的"英雄號"盾構(gòu)機為研究對象,針對盾構(gòu)在復(fù)雜地層施工時,常規(guī)PID算法無法滿足推進油缸速度同步控制的問題,提出單神經(jīng)元PID控制策略。通過AMESim建立液壓推進系統(tǒng)的物理模型,并利用Simulink設(shè)計出單神經(jīng)元控制器,最后進行聯(lián)合仿真,分析在不均突變載荷下各區(qū)間推進油缸的速度響應(yīng)特性。仿真結(jié)果表明,該控制策略與常規(guī)PID相比,調(diào)節(jié)時間縮短0.1s左右,振蕩幅值減小至原來的1/2內(nèi)。由此可得,采用單神經(jīng)元PID控制能夠有效地解決推進油缸速度同步性差的問題,為不良地質(zhì)環(huán)境下盾構(gòu)推進系統(tǒng)的同步控制提供了理論支撐。
[Abstract]:Taking the "Hero" shield machine in the section from Exi Lake East Station to Exi Lake West Station on Nanchang Metro Line 1 as the research object, aiming at the problem that the conventional PID algorithm can not meet the problem of synchronous control of the speed of propelling oil cylinder during the construction of shield machine in complex stratum. A single neuron PID control strategy is proposed. The physical model of hydraulic propulsion system is established by AMESim, and a single neuron controller is designed by using Simulink. Finally, the velocity response characteristics of each interval propulsion cylinder under uneven abrupt load are analyzed by joint simulation. The simulation results show that compared with the conventional PID, the control strategy shortens the adjusting time by about 0.1 s and reduces the oscillation amplitude to within 1 / 2 of the original value. It can be concluded that using single neuron PID control can effectively solve the problem of differential synchronism of propulsion cylinder velocity, and provide theoretical support for synchronous control of shield tunneling propulsion system under unfavorable geological environment.
