My intention is to have multiple non-related transfer functions then perform a unity feedback operation on them, all at once. My Code is as follows:
K=[1:2]';
pone=ones(1,length(K));
G=tf(mat2cell(K*conv([1 3],[1 5]),pone),conv([1 -2],[1 -4]));
T=feedback(G,pone);
I can't figure out why I'm not getting the right feedback output. For this case I get:
G =
From input to output...
s^2 + 8 s + 15
1: --------------
s^2 - 6 s + 8
2 s^2 + 16 s + 30
2: -----------------
s^2 - 6 s + 8
Continuous-time transfer function.
T =
From input to output...
0.25 s^2 + 2 s + 3.75
1: ---------------------
s^2 + 4.5 s + 13.25
0.5 s^2 + 4 s + 7.5
2: -------------------
s^2 + 4.5 s + 13.25
Continuous-time transfer function.

What feedback value are you expecting ?

Thanks for the quick response! I am expecting:
T =
From input to output...
s^2 + 8 s + 15
1: ---------------------
2s^2 + 2 s + 23
2 s^2 + 16 s + 30
2: -------------------
3 s^2 + 10 s + 38
Continuous-time transfer function.
Basically G/1+G; *sorry for the typo
