摘要
阀控非对称缸系统存在着大量的非线性和不确定因素,这些因素对系统稳定性的影响非常复杂。本文建立了阀控非对称缸系统的非线性模型,以此模型为基础,利用多参数分岔理论分析了单一因素变化和多个因素同时变化等不同状况下系统稳定性的变化,给出了增大系统稳定裕度的设计指导性意见。
A valve-controlled asymmetric cylinder system has many factors of nonlinearity and uncertainty, whose influence on the stability of the system is complicated. Its nonlinearity model is established and used as the basis for analyzing the variation of its stability with that of a single factor or multiple factors. In doing so, we adopt the multi-parameter bifurcaton theory and present our suggestions on how to increase the system＇s stability margin.
