摘要
对于以常系数偏微分方程描述的一维波动分布参数系统变换为以时间为独立变量的定常系统,用已知的常系数常微分方程系统的状态空间分析做了定性的判定。这种方法运免了直接处理分布参数系统的复杂数学方法。
This article presents the known qualitative analysis in state space for the time invarant System described by ordinary differential equations obtained by Laplace transforming the space variable x of an one-dimensional distributed parameter system of the first order partial differential equation of a lossless and homogeneous transmission line. In doing so, the tedious and complicated mathematics in direct treatments for systems of distributed parameters has been avoided.
