摘要
结合水下液压机械手线性关节的阀控非对称缸位置伺服系统,分析了阀控非对称缸的负载压力-流量特性,建立了阀控缸流量连续性方程和液压缸的力平衡方程,推导了阀控缸位置控制系统动态特性的数学模型,只增加负载环节就可以构成新的液压伺服系统模型。采用MAT-LAB软件对阀控缸位置控制系统进行动态特性仿真分析,验证了系统模型的正确性。
Based on asymmetric cylinder position servo system of linear joints of underwater hydraulic manipulator,Load pressure-flux characteristics of asymmetric cylinder controlled by servo-valve was analyzed.Flux continuity equation of cylinder controlled by servo-valve and the balance equation of hydraulic cylinder were established.The dynamic characteristics mathematics model for position control system in cylinder controlled by servo-valve was deduced,a new hydraulic servo control system would be obtained through changing load based on this model.MAT-LAB language software was used to carry through dynamic characteristics simulation analysis for position control system in cylinder controlled by servo-valve.
