Hi there! I need to write a program that evaluate the output flow from a tank when i change my setpoint value with a proportional controller. I wrote the following script but it doesn't work! Could u help me?
Clear["Global`*"];
A = 5;
cD = 0.8;
do = 0.15;
Ao = Pi*do^2/4;
Fi = 0.1;
Kc = -1;
hSS = (Fi/(Ao + cD))^2/(2*9.81);
FoSS = Fi;
tCambioSP = 10;
h = hSS;
Fo = FoSS;
F[t_] := {
If[t < 10, hSP = hSS, hSP = 2*hSS];
epsi = hSP - h;
Fo = FoSS + Kc*epsi;
h = h + (Fi - Fo)/A;
Fo}
Plot[F[c], {c, 0, 20}]
