So, I'm working on my control systems thesis, and I have an unecaseraly difficult closed lop trnsfer function.
My final task is to discuss the system robustness to a change in the damped natural frequency "wn" by adding 5% and 10% respectivelly. I need to plot the errors as a series of subplots.
In less specific examples, how could I have say a sine wave "x = sin(2*pi*f*t);" and have say a loop " for f = [10,15,20];" then have a series of three subplots for each respective frequency?
I should add having say:
x1 = sin(2*pi*f1*t)
x2 = sin(2*pi*f2*t)
x3 = sin(2*pi*f3*t)
Simply isnt an option here.

I don't really see a problem with just doing the obvious, something like:
f = [10, 15, 20];
t = ... % Whatever t is defined as
for n = 1:numel( f )
hAxes = subplot( 1, 3, n );
plot( hAxes, t, sin( 2 * pi * f( n ) * t ) );
end

Trouble is my overall closed loop tf is pretty complicated, repeating it several times would be very messy. I did figure out the olbvious solutin though. Thanks anyway buddy :)

Found my solution guys!
n=[1,2,3];
f=[10,15,20];
x(n) = sin(2*pi*f(n)*t);
