Hi @Maaz Madha
Assuming that the sensor measures perfectly (
), then this is one of the ways:
), then this is one of the ways:s = tf('s');
G = (13.11*s^3 + 30.28*s^2 - 17650*s - 692.3)/(s^5 + 19.97*s^4 + 150.1*s^3 + 12.95*s^2 + 26.24*s)
H = 1;
Gcl = G/(1 + G*H) % closed-loop transfer function
Gcl = minreal(Gcl) % minimal order of Gcl
pole(Gcl) % find the poles of Gcl
ans =
-14.6294 + 0i
-6.1635 + 11.5538i
-6.1635 - 11.5538i
7.0258 + 0i
-0.0393 + 0i
Since one of the poles is in the right-half s plane, then the system 
is unstable. You will need to design a compensator 
to stabilize it.
