基于AMESim仿真软件的平稳降压系统控制的建模与仿真

Modeling and simulation of steady pressure relief system control based on AMESim software

基于"50MN大型液压机平稳卸压"项目的需求,并结合已有的"驱动单元"~[1]专利技术,一种可连续平稳降压的驱动控制单元已被提出,硬件控制模块已经被设计出来并经过了试验,该控制单元主要是在液压缸的上腔形成一个封闭的空间,从而不需要考虑液压阀和部分管路对液压系统的控制产生的影响,前面的研究人员已经对该控制方案做了实际的验证,实验结果基本符合控制理论。本文主要是借助AMESim软件对该控制理论中涉及到的阀和步进电机等系统元件的控制信号进行一种时间上的逻辑建模,并对整个系统进行建模以及结果的仿真,从而来验证其控制的合理性。

Based on the project requirements of 50 MN large hydraulic machine steady pressure relief and combined with existing patented technology of drive unit.A kind of drive control unit was put forward which can reduce pressure continuously and smoothly,designed and tested the hardware control module.The control unit could form an enclosure space in hydraulic cylinder upper cavity and don^the influence of hydraulic valve and partial pipeline on the control of hydraulic system.The experimental results are in accordance with the control theory.In this paper,the control signals of valve and stepping motor and other system components were modeled by the AMESim software,and simulation result to verify the control rationality.
