控制系统中相关性能指标之间关系分析

Analysis of the Related Function Index of the Control System

本文比较详尽地推导和分析了二阶控制系统频域指标谐振频率及频宽与时域指标之间的关系，即ω_r 与ξ的关系、ω_r与 M_r 的关系、ω_b 与ξ的关系、ω_b 与 M_r 的关系，并编写了 MAILAB 程序，画出了关系曲线；从而对分析和设计控制系统带来了极大的方便。

In this paper,the writer analyses the relations between the frequency field index,collaborateconcussion frequency,frequency width and time field index of the two exponential control system in de-tails,that is to say,the relations between ω_r and ξ,ω_r and M_r,ω_b and ξ,ω_b and M_r.On the ba-sis,the writer edits the MATLAB programme,and shows the relationship curve.This brings great conve-nience to analyzing and designing the control system.
