How can calculate the rise time and settling time in simulink model with out m-file? it is useful to find the system response parameter during simulink simulation. it is required for my research work.

kindly,guide me for it.

Thanks

What I suggest is to log the data and then run stepinfo(). You can add this one line command to the StopFcn callback of the model so it will be completely automatic.

Hi, I have exported the data to Workspace from the scope, but I am unable to proceed with finding the rise time and settling time from there. Can you please guide me with an example? Any help would be greatly appreciated.

在 MATLAB Online 中打开

>> s=tf('s'); >> sys=(1/(s+1)); >> s = stepinfo(sys,'RiseTimeLimits',[0.05,0.95])

s =

        RiseTime: 2.9445
    SettlingTime: 3.9124
     SettlingMin: 0.9523
     SettlingMax: 0.9996
       Overshoot: 0
      Undershoot: 0
            Peak: 0.9996
        PeakTime: 7.8163
