浅议用Matlab绘制Bode图及频率特性分析

Drawing Bode Graphic with Matlab and Analysis of Frequency

在工程实践中,要求能比较简单迅速地分析出系统各参数对暂态特性的影响以及系统稳态性能的好坏。频率法是应用频率特性研究控制系统的一种重要方法,采用这种方法可直观地表达出系统的频率特性。根据系统的频率特性能间接地揭示系统某些环节或者参数对系统稳态特性和暂态特性的影响,并能指明改进系统的方向。而Matlab的介入,使得利用计算机来精确地绘制系统的各种频率特性成为现实。

In Engineering, we hope to analyse the effect of parameters of systems on transient state and the performance of stable of them. Frequency rules are important method which apply to using frequency performance to research controlling systems. And Matlab makes it become reality to employ computers to draw graphics of kinds of systems accurately.
