Hi, your system is unstable and it grows without bound, thus making the simulation stops. Check the formulas of each Gain block. This is a linear system, so you can check its stability before simulating the system.

this is my code in matlab: R1=6.8e+3;

R2=6.8e+3;

R3=4.7e+3;

C1=68e-9;

C2=10e-9;

u=5;

and these are my derivatives depending on x1 and x2

x1' = (-1/C1)*(1/R1-1/R3) *x1 + (-1/C1)*(1/R2-1/R3) ;1/(C2*R3) * x2 + 1/(C1 * R1) *u

x2'=1/(R3*C2)* x1 -1/(R3*C2)* x2

y=x1-x2

how will I have to make the connections?
