摘　　要：以在南昌地铁1号线艾溪湖东站至艾溪湖西站区间施工的"英雄号"盾构机为研究对象,针对盾构在复杂地层施工时,常规PID算法无法满足推进油缸速度同步控制的问题,提出单神经元PID控制策略。通过AMESim建立液压推进系统的物理模型,并利用Simulink设计出单神经元控制器,最后进行联合仿真,分析在不均突变载荷下各区间推进油缸的速度响应特性。仿真结果表明,该控制策略与常规PID相比,调节时间缩短0.1s左右,振荡幅值减小至原来的1/2内。由此可得,采用单神经元PID控制能够有效地解决推进油缸速度同步性差的问题,为不良地质环境下盾构推进系统的同步控制提供了理论支撑。Taking the＂Hero＂shield machine working in a certain section of Nanchang Metro Line1 station as the research object,aiming at the problem that conventional PID cannot guarantee the precision of propulsion cylinder synchronous control,the strategy of single neuron PID control was put forward.The physical model of hydraulic propulsion system was established by AMESim,and the single neuron controller was designed by Simulink.Finally,the synchronous control performance of the propulsion cylinder under the condition of different sudden change loads was analyzed by joint simulation.The simulation results showed that compared with conventional PID,the regulating time of the proposed control strategy was shortened about 0.1s,and the oscillation amplitude was reduced to the original 1/2.From the analysis of results,single neuron PID control can effectively solve the problem of propulsion cylinder synchronous control,which provides an effective theoretical support for the synchronous control of shield propulsion system under adverse geological environment.
