Question about system overshoot

[mazen_zone]

I want to get the maximum overshoot for a system whose steady state output is zero (the output is the deviation from an equilibrium point), substituting in the maximum overshoot formula |Ymax-Ys.s|/Ys.s will yield an infinity, so how to do it?

thanks

The maximum overshoot you can achieve is infinity, what's the problem? Why are you designing a system for maximum overshoot?

I need to get the minimum damping ratio and natural frequency
