基于LabVIEW技术的动态流量软测量模型研究∗

摘要

文章以伺服电机驱动定量泵输出流量为研究对象，分析了实时转速、压力、温度、油液粘度等变化对动态流量的影响，建立基于LabVIEW技术的动态流量软测量模型，并进行静态、动态及流量闭环控制实验分析，研究表明该模型有较高的稳态测量精度和优异的动态响应特性及闭环控制特性，为动态流量测量提供了一条新途径。%The research object is servo motor drive quantitative pump output flow, to analysis the effect of the real-time speed, pressure, temperature, oil viscosity etc changes on the influence of dynamic traffic, dy-namic flow soft measurement model is established based on LabVIEW technology and analysis for static, dy-namic and flow closed loop control experimental. Research shows that the model has a higher measuring pre-cision and excellent dynamic response and closed-loop control features, for the dynamic flow measurement provides a new way.
