Hi, I'd like to know please how to extract the "dot inflexion" from this program using Matlab software :
%Paramètres
Vin=24;R=10;L=1e-3;C=1e-6;T=1e-6;
c=[1 0;0 1];d=[0;0];
K=300;Vref=20;alpha=1.5e6
%Réponse indicielle
A=[0 -1/L;1/C -1/R/C]
B=[Vin/L;0]
C=[0 1]
D=0
[num,den]=SS2TF(A,B,C,D)
h=tf(num,den)
figure(1)
step(h,1e-3)
