hi all, I was wondering that when i plot a graph from Simuink, is there any way of determining the response parameters, like Steady-state error, Damping ratio and time to peak, without calculating them myself. I tried using LTIview but it doesn't let me open a Simulink plot.
Thanks
Johnny

Save the data that goes into the plot as workspace variables. Use the To Workspace block in Simulink.
Then use stepinfo command in Control System Toolbox: http://www.mathworks.com/help/toolbox/control/ref/stepinfo.html

Is there a way of determining them for a square wave, I should have mentioned that.

if your system is linear then you do not need the whole square wave. Just save the results that show system response to the first step, and use that as described in the answer.
