DGN液压加载控制器的闭环动态控制特性分析

The Dynamic Control Speciality Analysis of DGN Hydraulic Load Controller

DGN液压加载控制器是用于岩土工程测试的仪器。文章首先介绍DGN液压加载控制器的原理,然后对DGN液压加载控制器闭环动态控制特性进行了的分析。推导出应力控制时的线性动态系统(恒压输出控制系统)的相关传递函数和伯德图。最后,通过实验对理论分析进行了验证。

DGN hydraulic load controller is an instrument for engineering test on rock and soil. First,analysis and explain that DGN hydraulic load controller＇s principle . Then analyze dynamic speciality in closed loop of DGN hydraulic load controller. In succession deduct correlative transfer function and bode diagram of stress control＇s linear dynamical system （constant pressure output control system）. Finally, get across the experiment .Validate that the analysis result of dynamic speciality in closed loop is correct.
