本文用现代控制理论中的状态空间法拟定了YF—20H型溢流阀的数学模型,并用数字仿真的方法进行分析,较准确地得出了该阀的非线性动态特性,与试验进行比较两者较为吻合。
In this paper, the mathematical model of YF-20H relief valve is formulated by the state space method in modern control theory. The numerical simulation method is used to analyze the nonlinear dynamic characteristics of the YF-20H relief valve. Compared with the experimental results More consistent.
