So I've constructed a PID Controller using Simulink which has produced a plot.

I've then used Matlab to show this plot, we were told to do this as oppose to using the scope in Simulink.

However I am having trouble finding the settling time for this plot on Matlab. I've tried right clicking which is supposed to show a characteristics menu which shows settling time, overshoot etchowever when I right click nothing shows up.

I've also tried using this:

stepinfo(y,t,yfinal)

ans =

        RiseTime: NaN
    SettlingTime: NaN
     SettlingMin: NaN
     SettlingMax: NaN
       Overshoot: 0
      Undershoot: 0
            Peak: 0
        PeakTime: 67.810000000000002

However as you can see no settling time is shown.

How should I proceed?

Thanks.
