Using rlocus I am confused
显示 更早的评论
G = tf([1 1], conv([1 2 2], [1 2 5]));
rlocus(G, linspace(-8, 0, 1000), linspace(-10,10,1000))
title('Root Locus Diagram');
xlabel('Real Axis');
ylabel('Imaginary Axis');
Confused because it keeps giving me the same error and I am wondering if I need to format it differently or something

You appear to be overthinking it.
Try this —
G = tf([1 1], conv([1 2 2], [1 2 5]));
figure
rlocusplot(G)
grid
% title('Root Locus Diagram');
% xlabel('Real Axis');
% ylabel('Imaginary Axis');
The rlocusplot function has more options than rlocus, although it does not return the feedback gains. Use whatever of these functions you find best for your application.

Hi Madyson,
If you want to draw the root locus for a specific range of gains, then only specify a single range at a time
G = tf([1 1], conv([1 2 2], [1 2 5]));
figure
rlocus(G, linspace(-8, 0, 1000));
title('Root Locus Diagram');
xlabel('Real Axis');
ylabel('Imaginary Axis');
Or
G = tf([1 1], conv([1 2 2], [1 2 5]));
figure
rlocus(G, linspace(-10,10,1000));
title('Root Locus Diagram');
xlabel('Real Axis');
ylabel('Imaginary Axis');
