先导式溢流阀调压系统动态特性仿真研究

The dynamic characteristic simulation and reseach of the pilot-acting spill over valve

这里利用现代控制理论和现代建模方法—功率键合图法,建立先导式溢流阀调压系统数学模型,并应用MATLAB软件对其动态特性进行仿真分析,为该阀的性能评价和正确使用提供科学依据。

Use modern control theory and a power bond graph method for es ta blishing mathematical models of pilot- acting spillover valve.It also simulate and analyse the dynamic characteristic based on the MATLAB. So it provide scient ific basis for estimating the characteristic and correct using of the valve.
