Control systems: Labelling multiple plots dynamically based on parameter ?
显示 更早的评论
Hello! This is my first time using this forum. Basically I need some way to label the plots with the value of the variable 'zeta' so that my output (below)
resembles this diagram (below) in my text book (the numbers "1.5", "1.0", "0.8", etc):
The code I have used is:
s = tf('s');
Wn = 1;
for zeta = 0.1:0.1:0.9
T = Wn^2/(s^2 + 2*zeta*Wn*s + Wn^2);
step(T);
hold all
end

You can use this. May be it will help you.
s = tf('s');
Wn = 1;
i=1;
ti=linspace(0,20,200);
for zeta = 0.1:0.1:0.9
T = Wn^2/(s^2 + 2*zeta*Wn*s + Wn^2);
[a,b]=step(T,ti);
hold all
plot(b,a)
text(b(-i*2+40),a(-i*2+40),"\zeta="+string(zeta),'FontSize',10)
i=i+1;
end

Here's a way to do it with a legend.
s = tf('s');
Wn = 1;
for zeta = 0.1:0.1:0.9
T = Wn^2/(s^2 + 2*zeta*Wn*s + Wn^2);
[y,t]=step(T);
plot(t,y,'DisplayName',"zeta = "+string(zeta))
hold all
end
legend
