I have seen in some places the feedback function is called in the way "feedback(C*P,1)".
P = 1/(s^2 + 10*s + 20);
Kp = 300;
Kd = 10;
C = pid(Kp,0,Kd)
T = feedback(C*P,1)
t = 0:0.01:2;
step(T,t)
After searching for in the documentation,
I could not find a match.
could someone explain how feedback(C*P,1) is interpreted here?
