Generating; Rise Time, Overshoot etc from step input in Simulink

Firstly I'm an absolute beginner to Matlab/simulink. From a PID control system generated in simulink, I've plotted 2-d graphs from (tout & simout). The problem I have, is I cant right click on the graph to generate overshoot etc. Could you please give me step by step instructions (that a 10 year old could follow) to generate Overshoot, Settling time etc. Thanks

Please take a look at the stepinfo function. That's what you need to use.

>> 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
