摘　　要：挖掘机工作装置的控制存在结构上的时变性、液压系统的非线性,以及土壤的不确定性,很难找到完善的控制策略。提出利用虚拟仪器开发平台NILabVIEW开发液压挖掘机工作装置运动控制的测控系统,对液压系统的流量、压力、温度和液压缸的伸缩量等数据进行采集、显示,实现对液压系统的监测;利用MATLAB进行控制算法仿真,嵌入到LabVIEW中,实现对采集数据的处理,得到输出参数,实现对挖掘机工作装置运动的控制;通过LabVIEW开发的虚拟仪器监测系统的各个参数,实时观察各个参数的变化。Due to structure variation in real-time,nonlinear hydraulic system and uncertainty of soil property in the control for excavator attachment,a perfect control strategy is difficult to obtain. It is suggested that a monitor and control system for the movement of excavator attachment be developed on virtual instrument development platform NI LabVIEW to collect and display data of flow rate,pressure,temperature and cylinder position in hydraulic system to realize monitoring of hydraulic system. The control algorithm is edited and simulated with MATLAB and embedded into LabVIEW to process collected data and obtain output parameters in movement control of excavator attachment. Variation of every parameter can be observed in real-time through each parameter of virtual instrument monitoring system developed by LabVIEW.
