摘要:盾构推进液压系统是一个复杂的机、电、液耦合系统,具有非线性、时变性、易受施工工况影响的特点,很难建立其精确的数学模型。本文基于盾构推进液压系统的数学模型,提出模糊控制策略。将模糊自适应PID控制器应用于推进系统的控制,获得了良好的控制性能。仿真结果表明:该模糊控制器结构简单,可有效提高系统的实时性、稳定性和鲁棒性。

Abstract:The Thrust hydraulic system of shield is plex mechanical-electrical-hydraulic coupling to characteristics of non-linearity、deformation and being vulnerable to operation conditions,it was difficult to model for the control system fuzzy control strategy was proposed based on the mathematical model of the thrust hydraulic system of fuzzy self-turning PID controller was applied to control the thrust hydraulic system and good control performance was simulation results show that the contro
