关于控制系统相关命令绘图
如rlocus(sys)怎么用plot画出来？还有pzmap
请高手告知一下。
紧急，谢谢！
[ 本帖最后由 sigma665 于 2008-5-17 18:04 编辑 ] RLOCUSEvans root locus.
RLOCUS(SYS) computes and plots the root locus of the single-input,
single-output LTI model SYS.The root locus plot is used to
analyze the negative feedback loop
+-----+
---->O----->| SYS |----+---->
-| +-----+ |
| |
| +---+ |
+-------| K |<----+
+---+
and shows the trajectories of the closed-loop poles when the feedback
gain K varies from 0 to Inf.RLOCUS automatically generates a set of
positive gain values that produce a smooth plot. 不是很明白搂主的意图
搂主是想画根轨迹图吗？
rlocus本身就是一个绘图命令，举个例子
clear;close all
num=;den=;
rlocus(num,den);
又或者搂主是想用plot命令来实现rlocus的功能？
