Last time i was trying to show step response information. I used matlab function "stepinfo" and i compared the results with informations from step response characteristic. These times were different, even though it was that same plant. Why these times are different?
I also have problem with interpretation of the rise time as shown in picture below. Why the values of these times are the same, even though they are on different place on the time axis?

From my understanding and taking reference from the code. The stepinfo function is working fine if you look at the characterics of figure 1
figure, step(F_q*Gclz_q,F_o*Gclz_o,tfinal) ;
The above three lines of code would give the same characteristics.
But the plot you have mentioned is for
And the stepinfo is not called for these models. If you change the code to the one below. The correct step characterics would be displayes.
disp(['Parametry układu dynamicznego dla R = ' num2str(R)])
disp(['Parametry układu statycznego dla R = ' num2str(R)])
