二阶线性系统的仿真分析

The simulation analysis of linear system of two order

二阶线性系统的应用非常广泛,传统的分析方法是数学分析法.文章利用仿真的方法,主要研究了在给定典型输入信号下如何求取系统的输出信号并进行了分析,得出了二阶线性系统的响应随阻尼比不同而变化的情况,以及当自然频率的值减小时,脉冲响应的幅度也随着减小,响应的速度也将降低,反之亦然.

The linear system of two order which is widely applied to differe nt fields is traditionally analysized by the method of mathematical analysis. Thro ugh detailed simulation analysis, this article stresses on how to obtain systema tic out-put signals from given in-put signals, the linear system of two orde r varies with the changes of resisting force, that is, if the fixed frequency de clines, the range and speed responded by pulse will be on the decline; and vice versa.
