摘要
本文首先对加定差减压阀后变频液压泵控调速调压系统的优点作了简要介绍;随后建立了变频液压泵控调速调压系统的动态数学模型,将其化作状态方程模型,得出系统在阶跃信号输入下的各主要参数的输出响应。
This paper puts forward a kind of innovative system in which damp is equipped. Then establishes its dynamic mathematics model according to the system＂ s functional diagram, and simulate its nonlinear step character by using 4 order equation of Romberg- Pagoda, gets the output response of variable parameters under step signs.
