i got this systema represented by his transfer function (and the equations):
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/191155/image.jpeg)
i want to get the value of the output (surounded with a black circle)
and i got this code:
function xdot=diagrama_bloques_nuria(t,x)
Ka=10;
Kb=20;
Km=10;
Ra=10;
Ks=0.75;
Kf=1;
Jm=0.01;
Ke=0.25;
A=5;
Vp=5;
Vr=Vp*square(2*pi*t)+5;
Va=(Vr-Kf*x(1, :))*Ka;
xdot = [
(x(2, :)*Ke)-(x(1, :)*Ks);
x(3, :);
(Km/(Ra*Jm))*(Va-(Kb*x(3, :)));
];
%[t,x]=ode45('diagrama_bloques_nuria',[0,10],[0,0,0])
%plot(t, x(:, 1));
this code represent the system without the 1/A gain. But i don't know how to get the output with the 1/A gain.
