In this lecture observer based feedback controller is designed in matlab Simulink For complete design procedure Watch Video https://youtu.be/Lax3etc837U

1. In this Lecture we are going to design observer
based state feedback controller in Matlab
(Simulink).

2. First look at the block diagram

3. EQUATIONS ARE GIVEN BY

4. Lets start our example

5. A=[0 1 0
0 0 1
24 14 -1];
B=[0
0
1];
C=[2 -1 1];
%first we will check the Controllability and Observability
P=ctrb(A,B);
if rank(A)==rank(P)
disp('System is controllable')
else
disp('System is not controllable')
end
Write this code in m file and run it

6. Q=obsv(A,C);
if rank(A)==rank(Q)
disp('System is Observable')
else
disp('System is not Observable')
end
poles=[-5+5*1i -5-5*1i -10]; %desired poles
K=-acker(A, B , poles) %state feedback controller gain matrix
obpoles=[-20 -20 -20]
l=acker(A', C' , obpoles) %state feedback observer gain matrix
L=l'

7. AFTER YOU RUN THE M FILE OPEN SIMULINK
AND DESIGN YOUR OBSERVER LIKE THIS
