液压随动系统中存在多种非线性因素,对系统的动态特性及稳定性都有较大的影响。几十年来,许多学者在这方面做了大量的研究工作,如科罗鲍奇金和梅里特都研究过库伦摩擦力对机-液随动系统稳定性的影响,得出了某些结论。本文将用古典控制论的方法和微分方程组的数值解法,从理 There are many nonlinear factors in the hydraulic servo system, which have great influence on the dynamic characteristics and stability of the system. For decades, many scholars have done a great deal of research in this area. For example, Corrobacchin and Merritt have studied the effect of Coulomb friction on the stability of the MLC system and reached some conclusions. This article will use the classical method of control theory and numerical solution of differential equations, from the theory
