[Octave-bug-tracker] [bug #56560] [octave forge] (control) Error by addition of two frd objects

[Jonas Frischknecht]

Follow-up Comment #11, bug #56560 (project octave):

Sure. Here you go

% System to simulate measured vectors
Example_System = tf([1 10],[1 0.56 12]);
[Mag, Pha, W] = bode(Example_System);
% sampling time
Ts = 1e-3;
Tn = 1;
% Calculate complex response
for k=1:length(W)
   cmpl(k,1) = 10^(Mag(k)/20)*(cosd(Pha(k))+1i*sind(Pha(k)));
end
% Generate frd object
P = frd(cmpl,W,Ts);
% Controller
C = c2d(tf([Tn 1],[Tn 0]),Ts,'tustin');
% Calculate closed loop
OpLo = P*C;
T = OpLo/(1 + OpLo);
% plot bode
figure(1)
bode(P,C,OpLo,T)
